This article presents the first observation of the Cabibbo-suppressed decay $螞_c^+ \rightarrow n e^+ 谓_{e}$, utilizing $4.5~\mathrm{fb}^{-1}$ of electron-positron annihilation data collected with the BESIII detector. A novel Graph Neural Network based technique effectively separates signals from dominant backgrounds, notably $螞_c^+ \rightarrow 螞e^+ 谓_{e}$, achieving a statistical significance exceeding $10蟽$. The absolute branching fraction is measured to be $(3.57\pm0.34_{\mathrm{stat.}}\pm0.14_{\mathrm{syst.}})\times 10^{-3}$. For the first time, the CKM matrix element $\left|V_{cd}\right|$ is extracted via a charmed baryon decay as $0.208\pm0.011_{\rm exp.}\pm0.007_{\rm LQCD}\pm0.001_{蟿_{螞_c^+}}$. This work highlights a new approach to further understand fundamental interactions in the charmed baryon sector, and showcases the power of modern machine learning techniques in experimental high-energy physics. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2410.13515v2-abstract-full').style.display = 'none'; document.getElementById('2410.13515v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 15 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 17 October, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">27 pages, 5 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Nature Commun. 16, 681 (2025) </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2409.14410">arXiv:2409.14410</a> <span> [<a href="https://arxiv.org/pdf/2409.14410">pdf</a>, <a href="https://arxiv.org/format/2409.14410">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Lattice">hep-lat</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1007/s11433-024-2588-0">10.1007/s11433-024-2588-0 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Decay properties of light $1^{-+}$ hybrids </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-lat?searchtype=author&query=Liang%2C+J">Juzheng Liang</a>, <a href="/search/hep-lat?searchtype=author&query=Chen%2C+S">Siyang Chen</a>, <a href="/search/hep-lat?searchtype=author&query=Chen%2C+Y">Ying Chen</a>, <a href="/search/hep-lat?searchtype=author&query=Shi%2C+C">Chunjiang Shi</a>, <a href="/search/hep-lat?searchtype=author&query=Sun%2C+W">Wei Sun</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2409.14410v2-abstract-short" style="display: inline;"> We explore the decay properties of the isovector and isoscalar $1^{-+}$ light hybrids, $蟺_1$ and $畏_1$, in $N_f=2$ lattice QCD at a pion mass $m_蟺\approx 417~\mathrm{MeV}$.

The McNeile and Michael method is adopted to extract the effective couplings for individual decay modes, which are used to estimate the partial decay widths of $蟺_1(1600)$ and $畏_1(1855)$ by assuming SU(3) symmetry. The partial decay widths of $蟺_1(1600)$ are predicted to be $(螕_{b_1蟺}, 螕_{f_1(1285)蟺}, 螕_{蟻蟺}, 螕_{K^*\bar{K}}) = (325 \pm 75, \mathcal{O}(10), 52 \pm 7, 8.6 \pm 1.3)~\mathrm{MeV}$, and the total width is estimated to be $396 \pm 90~\mathrm{MeV}$, considering only statistical errors. If $畏_1(1855)$ and the $4.4蟽$ signal observed by BESIII (labeled as $畏_1(2200)$) are taken as the two mass eigenstates of the isoscalar $1^{-+}$ light hybrids in SU(3), then the dominant decay channel(s) of $畏_1(1855)$ ($畏_1(2200)$) is $K_1(1270)\bar{K}$ ($K_1(1270)\bar{K}$ and $K_1(1400)\bar{K}$) through the $1^{+(-)}0^{-(+)}$ mode. The vector-vector decay modes are also significant for the two $畏_1$ states. Using the mixing angle $伪\approx 22.7^\circ$ obtained from lattice QCD for the two $畏_1$ states, the total widths are estimated to be $螕_{畏_1(1855)}=282(85)~\mathrm{MeV}$ and $螕_{畏_1(2200)}=455(143)~\mathrm{MeV}$. The former is compatible with the experimental width of $畏_1(1855)$.

The systematic uncertainty of using the symmetric momentum subtraction (SMOM) scheme is also included. Eventually, we predict $m_u=2.45(22)(20)$ MeV, $m_d=4.74(11)(09)$ MeV, and $m_s=98.8(2.9)(4.7)$ MeV with the systematic uncertainties from lattice spacing determination, continuum extrapolation and renormalization constant included.

Based on the lattice data, we adopt two independent methods to determine the mixing angle between $螢_c$ and $螢_c'$. After making the chiral and continuum extrapolation, it is found that the mixing angle $胃$ is $1.2^{\circ}\pm0.1^{\circ}$, which seems insufficient to account for the large SU(3) symmetry breaking effects found in weak decays of charmed baryons. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2303.17865v2-abstract-full').style.display = 'none'; document.getElementById('2303.17865v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 26 April, 2023; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 31 March, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2211.04713">arXiv:2211.04713</a> <span> [<a href="https://arxiv.org/pdf/2211.04713">pdf</a>, <a href="https://arxiv.org/format/2211.04713">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Lattice">hep-lat</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> </div> <p class="title is-5 mathjax"> Triply charmed baryons mass decomposition from lattice QCD </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-lat?searchtype=author&query=Li%2C+J">Jin-Bo Li</a>, <a href="/search/hep-lat?searchtype=author&query=Gui%2C+L">Long-Cheng Gui</a>, <a href="/search/hep-lat?searchtype=author&query=Sun%2C+W">Wei Sun</a>, <a href="/search/hep-lat?searchtype=author&query=Liang%2C+J">Jian Liang</a>, <a href="/search/hep-lat?searchtype=author&query=Qin%2C+W">Wen Qin</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2211.04713v2-abstract-short" style="display: inline;"> We present the first calculation of the connected scalar matrix element and the momentum fraction of charm quark within the$\frac{3}{2}^{+}$ and $\frac{3}{2}^{-}$triply charmed baryons on lattice QCD.

The results are based on overlap valence fermions on two ensembles of $N_f=2+1$ domain wall fermion configurations with two lattice spacings. The corresponding sea quark pion masses are $300$ MeV and $278$ MeV. The separated contributions to the triply charmed baryon mass are derived through the decomposition of the QCD energy-momentum tensor. The contribution of the connected charm quark matrix element to the triply charmed baryon is about 3/2 times that of the charmonium. And it contributes almost 70\% of the total mass. The mass splitting of $\frac{3}{2}^{+}$ and $\frac{3}{2}^{-}$triply charmed baryons is mainly from $\langle H_{E}\rangle$ of the QCD energy-momentum tensor. A mass decomposition from the quark model is also studied for comparison. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2211.04713v2-abstract-full').style.display = 'none'; document.getElementById('2211.04713v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 29 December, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 9 November, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">11 page, 17 figures, Version for submission</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2209.08464">arXiv:2209.08464</a> <span> [<a href="https://arxiv.org/pdf/2209.08464">pdf</a>, <a href="https://arxiv.org/ps/2209.08464">ps</a>, <a href="https://arxiv.org/format/2209.08464">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Lattice">hep-lat</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1007/JHEP12(2022)033">10.1007/JHEP12(2022)033 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Partial wave analysis of the charmed baryon hadronic decay $螞_c^+\to螞蟺^+蟺^0$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-lat?searchtype=author&query=BESIII+Collaboration"> BESIII Collaboration</a>, <a href="/search/hep-lat?searchtype=author&query=Ablikim%2C+M">M.

This observation provides direct information on the internal dynamics of $T_{cc}^+(3875)$. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2206.06185v3-abstract-full').style.display = 'none'; document.getElementById('2206.06185v3-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 17 August, 2022; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 13 June, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> June 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">12 pages, 14 figures, version to appear in Physics Letters B</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2206.02724">arXiv:2206.02724</a> <span> [<a href="https://arxiv.org/pdf/2206.02724">pdf</a>, <a href="https://arxiv.org/format/2206.02724">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Lattice">hep-lat</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1103/PhysRevLett.130.061901">10.1103/PhysRevLett.130.061901 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Radiative Decay Width of $J/蠄\to 纬畏_{(2)}$ from $N_f=2$ Lattice QCD </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-lat?searchtype=author&query=Jiang%2C+X">Xiangyu Jiang</a>, <a href="/search/hep-lat?searchtype=author&query=Chen%2C+F">Feiyu Chen</a>, <a href="/search/hep-lat?searchtype=author&query=Chen%2C+Y">Ying Chen</a>, <a href="/search/hep-lat?searchtype=author&query=Gong%2C+M">Ming Gong</a>, <a href="/search/hep-lat?searchtype=author&query=Li%2C+N">Ning Li</a>, <a href="/search/hep-lat?searchtype=author&query=Liu%2C+Z">Zhaofeng Liu</a>, <a href="/search/hep-lat?searchtype=author&query=Sun%2C+W">Wei Sun</a>, <a href="/search/hep-lat?searchtype=author&query=Zhang%2C+R">Renqiang Zhang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2206.02724v2-abstract-short" style="display: inline;"> The large radiative production rate for pseudoscalar mesons in the $J/蠄$ radiative decay remains elusive.

The lattice simulation is carried out using $N_f=2$ lattice QCD gauge configurations at the pion mass $m_蟺 \approx 350$ MeV. In particular, the distillation method has been utilized to calculate light quark loops. The results are reported here with the mass $m_{畏_{(2)}}= 718(8)$ MeV and the decay width $螕(J/蠄\to纬畏_{(2)})=0.385(45)$ keV. By assuming the dominance of $\mathrm{U_A(1)}$ anomaly and flavor singlet-octet mixing angle $胃=-24.5^\circ$, the production rates for the physical $畏$ and $畏'$ in $J/蠄$ radiative decay are predicted to be $1.15(14)\times 10^{-3}$ and $4.49(53)\times 10^{-3}$, respectively, which agree well with the experimental measurement data. Our study manifests the potential of lattice QCD studies on the light hadron production in $J/蠄$ radiative decays. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2206.02724v2-abstract-full').style.display = 'none'; document.getElementById('2206.02724v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 11 February, 2023; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 6 June, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> June 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">6 pages, 4 figures, 2 tables</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.

The distillation method is adopted to treat the charm quark annihilation diagrams at a very precise level. For $1S$ charmonia, the charm quark annihilation effect almost does not change the $J/蠄$ mass, but lifts the $畏_c$ mass by approximately 3-4 MeV. For $1P$ charmonia, this effect results in positive mass shifts of approximately 1 MeV for $蠂_{c1}$ and $h_c$, but decreases the $蠂_{c2}$ mass by approximately 3 MeV. We have not obtain a reliable result for the mass shift of $蠂_{c0}$. In addition, it is observed that the spin averaged mass of the spin-triplet $1P$ charmonia is in a good agreement with the $h_c$, as expected by the non-relativistic quark model and measured by experiments. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2110.01755v2-abstract-full').style.display = 'none'; document.getElementById('2110.01755v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 7 March, 2022; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 4 October, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Chinese Phys.

By the assumption that $X(2370)$ is predominantly a pseudoscalar glueball, the mixing angle is determined to be approximately $4.6(6)^\circ$, which results in a $+3.9(9)$ MeV mass shift of the ground state pseudoscalar charmonium. In the mean time, the mixing can raise the total width of the pseudoscalar charmonium by 7.2(8) MeV, which explains to some extent the relative large total width of the $畏_c$ meson. As a result, the branching fraction of $畏_c\to 纬纬$ can be understood in this $c\bar{c}$-glueball mixing framework. On the other hand, the possible discrepancy of the theoretical predictions and the experimental results of the partial width of $J/蠄\to纬畏_c$ cannot be alleviated by the $c\bar{c}$-glueball mixing picture yet, which demands future precise experimental measurements of this partial width. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2107.12749v2-abstract-full').style.display = 'none'; document.getElementById('2107.12749v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 24 February, 2022; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 27 July, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">9 pages, 9 figures;v2: accepted by Physics Letter B</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">MSC Class:</span> 81T25 </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.

From the amplitude analysis, the $K^*(892)^+ K_S^0$ component is found to be dominant with a fraction of $(57.1\pm2.6\pm4.2)\%$, where the first uncertainty is statistical and the second systematic. In combination with the absolute branching fraction $\mathcal{B}(D^+\to K^+ K_S^0 蟺^0)$ measured by BESIII, we obtain $\mathcal{B}(D^+\to K^*(892)^+ K_S^0)=(8.69\pm0.40\pm0.64\pm0.51)\times10^{-3}$, where the third uncertainty is due to the branching fraction $\mathcal{B}(D^+\to K^+ K_S^0 蟺^0)$.

Weak decays of charm quarks can measure the coupling strength of quarks in different families and serve as an ideal probe for CP violation. As the lowest charm-strange baryons with three different flavors, $螢_c$ baryons (made of $csu$ or $csd$) have been extensively studied in experiments at the large hadron collider and in electron-positron collision. However the lack of reliable knowledge in theory becomes the unavoidable obstacle in the way. In this work, we use the state-of-the-art Lattice QCD techniques, and generate 2+1 clover fermion ensembles with two lattice spacings, $a=(0.108{\rm fm},0.080{\rm fm})$. We then present the first {\it ab-initio} lattice QCD determination of form factors governing $螢_{c}\to 螢\ell^+谓_{\ell}$, analogous with the notable $尾$-decay of nuclei. Our theoretical results for decay widths are consistent with and about two times more precise than the latest measurements by ALICE and Belle collaborations. Together with experimental measurements, we independently determine the quark-mixing matrix element $|V_{cs}|$, which is found in good agreement with other determinations. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2103.07064v2-abstract-full').style.display = 'none'; document.getElementById('2103.07064v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 22 January, 2022; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 11 March, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">6+1 pages, 4 figures; v2: 7 pages, corrected typos</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Chinese Physics C 46, 011002(2022) </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2012.06228">arXiv:2012.06228</a> <span> [<a href="https://arxiv.org/pdf/2012.06228">pdf</a>, <a href="https://arxiv.org/format/2012.06228">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Lattice">hep-lat</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1103/PhysRevD.103.094503">10.1103/PhysRevD.103.094503 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Gluons in charmoniumlike states </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-lat?searchtype=author&query=Sun%2C+W">Wei Sun</a>, <a href="/search/hep-lat?searchtype=author&query=Chen%2C+Y">Ying Chen</a>, <a href="/search/hep-lat?searchtype=author&query=Sun%2C+P">Peng Sun</a>, <a href="/search/hep-lat?searchtype=author&query=Yang%2C+Y">Yi-Bo Yang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="2012.06228v2-abstract-short" style="display: inline;"> The mass components of charmoniumlike states are investigated through the decomposition of QCD energy-momentum tensor (EMT) on lattice.

It is found that $\langle H_m\rangle$ is close to each other and around 2.0 to 2.2 GeV for these states, which implies that the mass splittings among these states come almost from the gluon contribution of QCD trace anomaly. The $\langle x\rangle$ of the $1^{-+}$ state is only around 0.55, while that in conventional charmonia is around 0.7 to 0.8.

We define the Bethe-Salpeter wave function $桅_n(r)$ in the Coulomb gauge as the matrix element of a spatially extended hybrid-like operator $\bar{c}{c}g$ between the vacuum and $n$-th state for each $J^{PC}$ with $r$ being the spatial separation between a localized $\bar{c}c$ component and the chromomagnetic strength tensor. These wave functions exhibit some similarities for states with the aforementioned different quantum numbers, and their $r$-behaviors (no node for the ground states and one node for the first excited states) imply that $r$ can be a meaningful dynamical variable for these states. Additionally, the mass splittings of the ground states and first excited states of charmonium-like hybrids in these channels are obtained for the first time to be approximately 1.2-1.4 GeV. These results do not support the flux-tube description of heavy-quarkonium-like hybrids in the Born-Oppenheimer approximation. In contrast, a charmonium-like hybrid can be viewed as a "color halo" charmonium for which a relatively localized color octet $\bar{c}c$ is surrounded by gluonic degrees of freedom, which can readily decay into a charmonium state along with one or more light hadrons.

When $q\bar{q}$ operator is included, we find the mass of this state does not change, and the $q\bar{q}$ operator couples very weakly to this state. So this state is most likely a glueball state. For pseudoscalars, along with the exiting lattice results, our study implies that both the conventional $q\bar{q}$ state $畏_2$ (or $畏'$ in flavor $SU(3)$) and a heavier glueball-like state with a mass of roughly 2.6 GeV exist in the spectrum of lattice QCD with dynamical quarks. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1711.00711v1-abstract-full').style.display = 'none'; document.getElementById('1711.00711v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 2 November, 2017; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2017. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">8 pages, 3 figures, 3 tables, talk presented at the 35th International Symposium on Lattice Field Theory, 18-24 June 2017, Granada, Spain</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> EPJ Web of Conferences 175, 05016 (2018) </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1702.08174">arXiv:1702.08174</a> <span> [<a href="https://arxiv.org/pdf/1702.08174">pdf</a>, <a href="https://arxiv.org/format/1702.08174">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Lattice">hep-lat</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1088/1674-1137/42/9/093103">10.1088/1674-1137/42/9/093103 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Glueball spectrum from $N_f=2$ lattice QCD study on anisotropic lattices </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-lat?searchtype=author&query=Sun%2C+W">Wei Sun</a>, <a href="/search/hep-lat?searchtype=author&query=Gui%2C+L">Long-Cheng Gui</a>, <a href="/search/hep-lat?searchtype=author&query=Chen%2C+Y">Ying Chen</a>, <a href="/search/hep-lat?searchtype=author&query=Gong%2C+M">Ming Gong</a>, <a href="/search/hep-lat?searchtype=author&query=Liu%2C+C">Chuan Liu</a>, <a href="/search/hep-lat?searchtype=author&query=Liu%2C+Y">Yu-Bin Liu</a>, <a href="/search/hep-lat?searchtype=author&query=Liu%2C+Z">Zhaofeng Liu</a>, <a href="/search/hep-lat?searchtype=author&query=Ma%2C+J">Jian-Ping Ma</a>, <a href="/search/hep-lat?searchtype=author&query=Zhang%2C+J">Jian-Bo Zhang</a> </p> <p class="abstract mathjax"> <span class="has-text-black-bis has-text-weight-semibold">Abstract</span>: <span class="abstract-short has-text-grey-dark mathjax" id="1702.08174v2-abstract-short" style="display: inline;"> The lowest-lying glueballs are investigated in lattice QCD using $N_f=2$ clover Wilson fermion on anisotropic lattices.

We simulate at two different and relatively heavy quark masses, corresponding to physical pion mass of $m_蟺\sim 938$ MeV and $650$ MeV. The quark mass dependence of the glueball masses have not been investigated in the present study. Only the gluonic operators built from Wilson loops are utilized in calculating the corresponding correlation functions. In the tensor channel, we obtain the ground state mass to be 2.363(39) GeV and 2.384(67) GeV at $m_蟺\sim 938$ MeV and $650$ MeV, respectively. In the pseudoscalar channel, when using the gluonic operator whose continuum limit has the form of $蔚_{ijk}TrB_iD_jB_k$, we obtain the ground state mass to be 2.573(55) GeV and 2.585(65) GeV at the two pion masses. These results are compatible with the corresponding results in the quenched approximation. In contrast, if we use the topological charge density as field operators for the pseudoscalar, the masses of the lowest state are much lighter (around 1GeV) and compatible with the expected masses of the flavor singlet $q\bar{q}$ meson. This indicates that the operator $蔚_{ijk}TrB_iD_jB_k$ and the topological charge density couple rather differently to the glueball states and $q\bar{q}$ mesons. The observation of the light flavor singlet pseudoscalar meson can be viewed as the manifestation of effects of dynamical quarks. In the scalar channel, the ground state masses extracted from the correlation functions of gluonic operators are determined to be around 1.4-1.5 GeV, which is close to the ground state masses from the correlation functions of the quark bilinear operators. In all cases, the mixing between glueballs and conventional mesons remains to be further clarified in the future. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1702.08174v2-abstract-full').style.display = 'none'; document.getElementById('1702.08174v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 7 September, 2018; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 27 February, 2017; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2017. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">14 pages, 8 figures, 9 tables; typos fixed, minor modifications, match the published version</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Chin.Phys.

Through a mixed action formalism (overlap valence on domain wall sea), the energy of the $q\bar{q}$ component is derived at different valence quark masses, and shows a linear dependence on $m_蟺^2$. The slope is determined to be $c_1=0.505(3)\,{\rm GeV}^{-1}$, from which the valence $蟺蟻$ sigma term is extracted to be $蟽_{蟺蟻}^{(\rm val)}=9.82(6)$ MeV using the Feynman-Hellman theorem. At the physical pion mass, the mass of the $q\bar{q}$ component is interpolated to be $m_蟻=775.9\pm 6.0\pm 1.8$ MeV, which is close to the $蟻$ resonance mass. We also obtain the leptonic decay constant of the $q\bar{q}$ component to be $f_{蟻^-}=208.5\pm 5.5\pm 0.9$ MeV, which can be compared with the experimental value $f_蟻^{\rm exp}\approx 221$ MeV through the relation $f_蟻^{\rm exp}=\sqrt{Z_蟻}f_{蟻^\pm} $ with $Z_蟻\approx 1.13$ being the on-shell wavefunction renormalization of $蟻$ owing to the $蟻-蟺$ interaction. We emphasize that $m_蟻$ and $f_蟻$ of the $q\bar{q}$ component, which are obtained for the first time from QCD, can be taken as the input parameters of $蟻$ in effective field theory studies where $蟻$ acts as a fundamental degree of freedom. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1507.02541v2-abstract-full').style.display = 'none'; document.getElementById('1507.02541v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 14 June, 2018; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 9 July, 2015; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2015. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">7 pages, 4 figures.

In this result one finds a straightforward explanation of a mismatch between extant estimates of the pion susceptibility. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('0912.2687v1-abstract-full').style.display = 'none'; document.getElementById('0912.2687v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 14 December, 2009; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2009. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">4 pages</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.Rev.C81:032201,2010 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/0812.2956">arXiv:0812.2956</a> <span> [<a href="https://arxiv.org/pdf/0812.2956">pdf</a>, <a href="https://arxiv.org/ps/0812.2956">ps</a>, <a href="https://arxiv.org/format/0812.2956">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Nuclear Theory">nucl-th</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Lattice">hep-lat</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1103/PhysRevC.79.035209">10.1103/PhysRevC.79.035209 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Chiral susceptibility and the scalar Ward identity </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-lat?searchtype=author&query=Chang%2C+L">Lei Chang</a>, <a href="/search/hep-lat?searchtype=author&query=Liu%2C+Y">Yu-xin Liu</a>, <a href="/search/hep-lat?searchtype=author&query=Roberts%2C+C+D">Craig D.

This follows directly from the expression for the vacuum quark condensate so long as a nonperturbative symmetry preserving truncation scheme is employed. For QCD in-vacuum the susceptibility can rigorously be defined via a Pauli-Villars regularisation procedure. Owing to the scalar Ward identity, irrespective of the form or Ansatz for the kernel of the gap equation, the consistent scalar vertex at zero total momentum can automatically be obtained and hence the consistent susceptibility. This enables calculation of the chiral susceptibility for markedly different vertex Ansaetze. For the two cases considered, the results were consistent and the minor quantitative differences easily understood. The susceptibility can be used to demarcate the domain of coupling strength within a theory upon which chiral symmetry is dynamically broken. Degenerate massless scalar and pseudoscalar bound-states appear at the critical coupling for dynamical chiral symmetry breaking. <a class="is-size-7" style="white-space: nowrap;"
