The Muon Collider Study (MuC) covers the accelerator complex, detectors and physics for a future muon collider. In 2023, European Commission support was obtained for a design study of a muon collider (MuCol) [3]. This project started on 1st March 2023, with work-packages aligned with the overall muon collider studies. In preparation of and during the 2021-22 U.S. Snowmass process, the muon collider project parameters, technical studies and physics performance studies were performed and presented in great detail. Recently, the P5 panel [4] in the U.S. recommended a muon collider R&D, proposed to join the IMCC and envisages that the U.S. should prepare to host a muon collider, calling this their "muon shot". In the past, the U.S. Muon Accelerator Programme (MAP) [5] has been instrumental in studies of concepts and technologies for a muon collider. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2407.12450v2-abstract-full').style.display = 'none'; document.getElementById('2407.12450v2-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> 28 January, 2025; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 17 July, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 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">This document summarises the International Muon Collider Collaboration (IMCC) progress and status of the Muon Collider R&D programme</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2311.15071">arXiv:2311.15071</a> <span> [<a href="https://arxiv.org/pdf/2311.15071">pdf</a>, <a href="https://arxiv.org/format/2311.15071">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> </div> </div> <p class="title is-5 mathjax"> Model-independent extraction of form factors and $|V_{cb}|$ in $\overline{B} \rightarrow D \ell^- \overline谓_\ell$ with hadronic tagging at BaBar </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=BaBar+Collaboration"> BaBar Collaboration</a>, <a href="/search/?searchtype=author&query=Lees%2C+J+P">J.

Here, $\ell$ denotes the light charged leptons $e$ and $渭$. A novel data-driven signal-background separation procedure with minimal dependence on simulation is developed. This procedure preserves all multi-dimensional correlations present in the data. The expected $\sin^2胃_\ell$ dependence of the differential decay rate in the Standard Model is demonstrated, where $胃_\ell$ is the lepton helicity angle. Including input from the latest lattice QCD calculations and previously available experimental data, the underlying form factors are extracted using both model-independent (BGL) and dependent (CLN) methods. Comparisons with lattice calculations show flavor SU(3) symmetry to be a good approximation in the $B_{(s)}\to D_{(s)}$ sector. Using the BGL results, the CKM matrix element $|V_{cb}|=(41.09\pm 1.16)\times 10^{-3}$ and the Standard Model prediction of the lepton-flavor universality violation variable $\mathcal{R}(D)=0.300\pm 0.004$, are extracted. The value of $|V_{cb}|$ from $\overline{B} \rightarrow D \ell^- \overline谓_\ell$ tends to be higher than that extracted using $\overline{B} \rightarrow D \ell^- \overline谓_\ell$. The Standard Model $\mathcal{R}(D)$ calculation is at a $1.97蟽$ tension with the latest HFLAV experimental average. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2311.15071v1-abstract-full').style.display = 'none'; document.getElementById('2311.15071v1-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> 25 November, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2303.08533">arXiv:2303.08533</a> <span> [<a href="https://arxiv.org/pdf/2303.08533">pdf</a>, <a href="https://arxiv.org/format/2303.08533">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Accelerator Physics">physics.acc-ph</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"> Towards a Muon Collider </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Accettura%2C+C">Carlotta Accettura</a>, <a href="/search/?searchtype=author&query=Adams%2C+D">Dean Adams</a>, <a href="/search/?searchtype=author&query=Agarwal%2C+R">Rohit Agarwal</a>, <a href="/search/?searchtype=author&query=Ahdida%2C+C">Claudia Ahdida</a>, <a href="/search/?searchtype=author&query=Aim%C3%A8%2C+C">Chiara Aim猫</a>, <a href="/search/?searchtype=author&query=Amapane%2C+N">Nicola Amapane</a>, <a href="/search/?searchtype=author&query=Amorim%2C+D">David Amorim</a>, <a href="/search/?searchtype=author&query=Andreetto%2C+P">Paolo Andreetto</a>, <a href="/search/?searchtype=author&query=Anulli%2C+F">Fabio Anulli</a>, <a href="/search/?searchtype=author&query=Appleby%2C+R">Robert Appleby</a>, <a href="/search/?searchtype=author&query=Apresyan%2C+A">Artur Apresyan</a>, <a href="/search/?searchtype=author&query=Apyan%2C+A">Aram Apyan</a>, <a href="/search/?searchtype=author&query=Arsenyev%2C+S">Sergey Arsenyev</a>, <a href="/search/?searchtype=author&query=Asadi%2C+P">Pouya Asadi</a>, <a href="/search/?searchtype=author&query=Mahmoud%2C+M+A">Mohammed Attia Mahmoud</a>, <a href="/search/?searchtype=author&query=Azatov%2C+A">Aleksandr Azatov</a>, <a href="/search/?searchtype=author&query=Back%2C+J">John Back</a>, <a href="/search/?searchtype=author&query=Balconi%2C+L">Lorenzo Balconi</a>, <a href="/search/?searchtype=author&query=Bandiera%2C+L">Laura Bandiera</a>, <a href="/search/?searchtype=author&query=Barlow%2C+R">Roger Barlow</a>, <a href="/search/?searchtype=author&query=Bartosik%2C+N">Nazar Bartosik</a>, <a href="/search/?searchtype=author&query=Barzi%2C+E">Emanuela Barzi</a>, <a href="/search/?searchtype=author&query=Batsch%2C+F">Fabian Batsch</a>, <a href="/search/?searchtype=author&query=Bauce%2C+M">Matteo Bauce</a>, <a href="/search/?searchtype=author&query=Berg%2C+J+S">J.

We present a search for $B \rightarrow 螞蠄_D$ decays using data collected by the $BABAR$ experiment at SLAC. This reaction is identified by fully reconstructing the accompanying $B$ meson and requiring the presence of a single $螞$ baryon in the remaining particles. No significant signal is observed, and bounds on the $B \rightarrow 螞蠄_D$ branching fraction are derived in the range $0.13 - 5.2\times 10^{-5}$ for $1.0 < m_{蠄_D} < 4.2$ GeV/$c^{2}$.

The idea of a muon collider is very appealing since it would allow to study particle collisions at up to tens of TeV energy, while offering a cleaner experimental environment with respect to hadronic colliders. One key element in the muon collider design is the low-emittance muon production. Recently,the Low EMittance Muon Accelerator (LEMMA) collaboration has explored the muon pair production close to its kinematic threshold by annihilating 45 GeV positrons with electrons in a low Z material target. In this configuration, muons are emerging from the target with a naturally low-emittance. In this paper we describe the performance of a system, to study this production mechanism, that consists in several segmented absorbers with alternating active layers composed of fast Cherenkov detectors together with a muon identification technique based on this detector. Passive layers were made of tungsten. We collected data corresponding to muon and electron beams produced at the H2 line in the North Area of the European Organization for Nuclear Research (CERN) in September 2018. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2105.12624v4-abstract-full').style.display = 'none'; document.getElementById('2105.12624v4-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> 31 October, 2021; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 26 May, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2021. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2005.01230">arXiv:2005.01230</a> <span> [<a href="https://arxiv.org/pdf/2005.01230">pdf</a>, <a href="https://arxiv.org/format/2005.01230">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> </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.125.241801">10.1103/PhysRevLett.125.241801 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Precision measurement of the ${\cal B}(违(3S)\to蟿^+蟿^-)/{\cal B}(违(3S)\to渭^+渭^-)$ ratio </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Lees%2C+J+P">J.

The uncertainty in ${\cal R}_{蟿渭}^{违(3S)}$ is almost an order of magnitude smaller than the only previous measurement. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2005.01230v2-abstract-full').style.display = 'none'; document.getElementById('2005.01230v2-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> 10 May, 2020; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 3 May, 2020; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2020. </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, 4 figures, 3 tables</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> BABAR-PUB-20/002, SLAC-PUB-17527 </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.

The LEMMA project is investigating the possibility of producing low emittance muon/antimuon pairs from the e$^+$e$^-$ annihilation process at threshold energy, resulting in small transverse emittance beams without any additional beam cooling. However most of the measurements available are performed at higher $\sqrt{s}$ values. It is therefore necessary to measure muons production in positron annihilation at threshold energy and compare the experimental results with the predictions in this specific energy regime. Apart from being a topic of physical interest by itself, these near to threshold measurements can have a sizeable impact on the estimation of the ultimate luminosity achievable in a muon collider with the LEMMA injection scheme. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1909.13716v2-abstract-full').style.display = 'none'; document.getElementById('1909.13716v2-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> 10 January, 2020; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 30 September, 2019; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 2019. </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">13 pages, 8 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> 2020 JINST 15 P01036 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1908.07425">arXiv:1908.07425</a> <span> [<a href="https://arxiv.org/pdf/1908.07425">pdf</a>, <a href="https://arxiv.org/format/1908.07425">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> </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.100.111101">10.1103/PhysRevD.100.111101 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Search for $B^- \to 螞\bar p 谓\bar谓$ with the BABAR experiment </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=The+BABAR+Collaboration"> The BABAR Collaboration</a>, <a href="/search/?searchtype=author&query=Lees%2C+J+P">J.

Signal $B^- \to 螞{\overline p} 谓{\overline谓}$ candidates are identified by first fully reconstructing a $B^+$ decay in one of many possible exclusive decays to hadronic final states, then examining detector activity that is not associated with this reconstructed $B^+$ decay for evidence of a signal $B^- \to 螞{\overline p} 谓{\overline谓}$ decay. The data yield is found to be consistent with the expected background contribution under a null signal hypothesis, resulting in an upper limit of ${{\cal B} (B^- \to 螞{\overline p} 谓{\overline谓}) < 3.0\times 10^{-5}}$ at the $90\%$ confidence level. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1908.07425v2-abstract-full').style.display = 'none'; document.getElementById('1908.07425v2-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> 10 December, 2019; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 20 August, 2019; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> August 2019. </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">10 pages, 7 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> BABAR-PUB-18/010, SLAC-PUB-17455 </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.

In this paper a layout of a positron driven muon source known as the Low EMittance Muon Accelerator (LEMMA) concept is presented. The positron beam, stored in a ring with high energy acceptance and low emittance, is extracted and driven to a multi-target system, to produce muon pairs at threshold. This solution alleviates the issues related to the power deposited and the integrated Peak Energy Density Deposition (PEDD) on the targets. Muons produced in the multi-target system will then be accumulated before acceleration and injection in the collider. A multi-target line lattice has been designed to cope with the focusing of both the positron and muon beams. Studies on the number, material and thickness of the targets have been carried out. A general layout of the overall scheme and a description is presented, as well as plans for future R&D. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1905.05747v2-abstract-full').style.display = 'none'; document.getElementById('1905.05747v2-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> 19 May, 2019; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 14 May, 2019; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2019. </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">18 pages, 32 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1905.00608">arXiv:1905.00608</a> <span> [<a href="https://arxiv.org/pdf/1905.00608">pdf</a>, <a href="https://arxiv.org/format/1905.00608">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> </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.124.071802">10.1103/PhysRevLett.124.071802 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Search for rare or forbidden decays of the $D^{0}$ meson </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Lees%2C+J+P">J.

We measure $\sin{2尾} = 0.80 \pm 0.14 \,(\rm{stat.}) \pm 0.06 \,(\rm{syst.}) \pm 0.03 \,(\rm{model})$ and $\cos{2尾} = 0.91 \pm 0.22 \,(\rm{stat.}) \pm 0.09 \,(\rm{syst.}) \pm 0.07 \,(\rm{model})$. The result for the direct measurement of the angle is $尾= \left( 22.5 \pm 4.4 \,(\rm{stat.}) \pm 1.2 \,(\rm{syst.}) \pm 0.6 \,(\rm{model}) \right)^{\circ}$. The last quoted uncertainties are due to the composition of the $D^{0} \to K_{S}^{0} 蟺^{+} 蟺^{-}$ decay amplitude model, which is newly established by a Dalitz plot amplitude analysis of a high-statistics $e^{+}e^{-} \to c\bar{c}$ data sample as part of this analysis. We find the first evidence for $\cos2尾>0$ at the level of $3.7$ standard deviations. The measurement excludes the trigonometric multifold solution $蟺/2 - 尾= (68.1 \pm 0.7)^{\circ}$ at the level of $7.3$ standard deviations and therefore resolves an ambiguity in the determination of the apex of the CKM Unitarity Triangle. The hypothesis of $尾= 0^{\circ}$ is ruled out at the level of $5.1$ standard deviations, and thus CP violation is observed in $B^{0} \to D^{(*)} h^{0}$ decays. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1804.06153v1-abstract-full').style.display = 'none'; document.getElementById('1804.06153v1-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 April, 2018; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 2018. </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">To be submitted to Physical Review D</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.

The main topics discussed are: (i) parton radiation and parton-to-hadron fragmentation functions (splitting functions at NNLO, small-$z$ NNLL resummations, global FF fits including Monte Carlo (MC) and neural-network analyses of the latest Belle/BaBar high-precision data, parton shower MC generators), (ii) jet properties (quark-gluon discrimination, $e^+e^-$ event shapes and multi-jet rates at NNLO+N$^{n}$LL, jet broadening and angularities, jet substructure at small-radius, jet charge determination, $e^+e^-$ jet reconstruction algorithms), (iii) heavy-quark jets (dead cone effect, charm-bottom separation, gluon-to-$b\bar{b}$ splitting), and (iv) non-perturbative QCD phenomena (colour reconnection, baryon and strangeness production, Bose-Einstein and Fermi-Dirac final-state correlations, colour string dynamics: spin effects, helix hadronization). <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1702.01329v1-abstract-full').style.display = 'none'; document.getElementById('1702.01329v1-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> 4 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">181 pages, 120 figures.

We measure branching fractions for decays with intermediate $危_{c}$ baryons to be ${\cal B}[\bar{B}^{0}\rightarrow危_{c}(2455)^{++}\bar{p}蟺^{-}]=(21.3 \pm 1.0 \pm 1.0 \pm 5.5) \times 10^{-5}$, ${\cal B}[\bar{B}^{0}\rightarrow危_{c}(2520)^{++}\bar{p}蟺^{-}]=(11.5\pm 1.0 \pm 0.5 \pm 3.0)\times 10^{-5}$, ${\cal B}[\bar{B}^{0}\rightarrow危_{c}(2455)^{0}\bar{p}蟺^{+}]=(9.1 \pm 0.7 \pm 0.4 \pm 2.4)\times10^{-5}$, and ${\cal B}[\bar{B}^{0}\rightarrow危_{c}(2520)^{0}\bar{p}蟺^{+}]= (2.2 \pm 0.7 \pm 0.1\pm 0.6) \times 10^{-5}$, where the uncertainties are statistical, systematic, and due to the uncertainty on the $螞_{c}^{+}\rightarrow\proton\Km蟺^{+}$ branching fraction, respectively. For decays without $危_{c}(2455)$ or $危_{c}(2520)$ resonances, we measure ${\cal B}[\bar{B}^{0}\rightarrow螞_{c}^{+}\bar{p}蟺^{+}蟺^{-}]_{\mathrm{non-危_{c}}}=(79 \pm 4 \pm 4 \pm 20)\times10^{-5}$. The total branching fraction is determined to be ${\cal B}[\bar{B}^{0}\rightarrow螞_{c}^{+}\bar{p}蟺^{+}蟺^{-}]_{\mathrm{total}}=(123 \pm 5 \pm 7 \pm 32)\times10^{-5}$. We examine multibody mass combinations in the resonant three-particle $危_{c}\bar{p}蟺$ final states and in the four-particle $螞_{c}^{+}\bar{p}蟺^{+}蟺^{-}$ final state, and observe different characteristics for the $\bar{p}蟺$ combination in neutral versus doubly-charged $危_{c}$ decays. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1302.0191v2-abstract-full').style.display = 'none'; document.getElementById('1302.0191v2-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> 28 March, 2013; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 1 February, 2013; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2013. </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">20 pages, 30 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> Babar-PUB-12/028, SLAC-PUB-15363 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1212.1856">arXiv:1212.1856</a> <span> [<a href="https://arxiv.org/pdf/1212.1856">pdf</a>, <a href="https://arxiv.org/ps/1212.1856">ps</a>, <a href="https://arxiv.org/format/1212.1856">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> </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.87.052010">10.1103/PhysRevD.87.052010 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Search for direct CP-violation in singly-Cabibbo suppressed D+- --> K+ K- pi+- decays </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=BaBar+Collaboration"> BaBar Collaboration</a>, <a href="/search/?searchtype=author&query=Lees%2C+J+P">J.

The analysis uses events in which the signal B decays are reconstructed with a loose neutrino reconstruction technique. We obtain partial branching fractions in several bins of q^2, the square of the momentum transferred to the lepton-neutrino pair, for B^0 --> pi^- l^+ nu, B^+ --> pi^0 l^+ nu, B^+ --> omega l^+ nu and B^+ --> eta l^+ nu. From these distributions, we extract the form-factor shapes f_+(q^2) and the total branching fractions BF(B^0 --> pi^- l^+ nu) = (1.45 +/- 0.04_{stat} +/- 0.06_{syst})x10^-4 (combined pi^- and pi^0 decay channels assuming isospin symmetry), BF(B^+ --> omega l^+ nu) = (1.19 +/- 0.16_{stat} +/- 0.09_{syst})x10^-4 and BF(B^+ --> eta l^+ nu) = (0.38 +/- 0.05_{stat} +/- 0.05_{syst})x10^-4. We also measure BF(B^+ --> eta^' l^+ nu) = (0.24 +/- 0.08_{stat} +/- 0.03_{syst})x10^-4. We obtain values for the magnitude of the CKM matrix element V_{ub} by direct comparison with three different QCD calculations in restricted q^2 ranges of B --> pi l^+ nu decays. From a simultaneous fit to the experimental data over the full q^2 range and the FNAL/MILC lattice QCD predictions, we obtain |V_{ub}| = (3.25 +/- 0.31)x10^-3, where the error is the combined experimental and theoretical uncertainty. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1208.1253v2-abstract-full').style.display = 'none'; document.getElementById('1208.1253v2-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> 6 November, 2012; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 6 August, 2012; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> August 2012. </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">35 pages, 14 figures, submitted to PRD</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> BABAR-PUB12/015; SLAC-PUB-15208 </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.Rev.D86:092004,2012 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1201.5677">arXiv:1201.5677</a> <span> [<a href="https://arxiv.org/pdf/1201.5677">pdf</a>, <a href="https://arxiv.org/ps/1201.5677">ps</a>, <a href="https://arxiv.org/format/1201.5677">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> </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.85.112009">10.1103/PhysRevD.85.112009 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Initial-State Radiation Measurement of the e+e- -> pi+pi-pi+pi- Cross Section </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=Lees%2C+J+P">J.

In addition to the charmed baryons we observe on average 2.6 \pm 0.2 charged intermediate mesons, predominantly pions, carrying 65% of the remaining energy. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1006.2216v1-abstract-full').style.display = 'none'; document.getElementById('1006.2216v1-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 June, 2010; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> June 2010. </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 postscript figures, submitted to Phys.Rev D-RC</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> BABAR-PUB-07/27, SLAC-PUB-14157 </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.Rev.D82:091102,2010 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/0901.0512">arXiv:0901.0512</a> <span> [<a href="https://arxiv.org/pdf/0901.0512">pdf</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> </div> </div> <p class="title is-5 mathjax"> Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=The+ATLAS+Collaboration"> The ATLAS Collaboration</a>, <a href="/search/?searchtype=author&query=Aad%2C+G">G.

The workshop gathered both theorists and experimentalists to discuss the current status of investigations of quark and gluon fragmentation into hadrons at different accelerator facilities (LEP, B-factories, JLab, HERA, RHIC, and Tevatron) as well as preparations for extension of these studies at the LHC. The main physics topics covered were: (i) light-quark and gluon fragmentation in the vacuum including theoretical (global fits analyses and MLLA) and experimental (data from e+e-, p-p, e-p collisions) aspects, (ii) strange and heavy-quark fragmentation, (iii) parton fragmentation in cold QCD matter (nuclear DIS), and (iv) medium-modified fragmentation in hot and dense QCD matter (high-energy nucleus-nucleus collisions). These mini-proceedings consist of an introduction and short summaries of the talks presented at the meeting. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('0804.2021v1-abstract-full').style.display = 'none'; document.getElementById('0804.2021v1-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> 12 April, 2008; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 2008. </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">43 pages, mini-proceedings Workshop ECT*, Trento, Feb. 25 - 29, 2008</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/0710.4451">arXiv:0710.4451</a> <span> [<a href="https://arxiv.org/pdf/0710.4451">pdf</a>, <a href="https://arxiv.org/ps/0710.4451">ps</a>, <a href="https://arxiv.org/format/0710.4451">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> </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.77.092002">10.1103/PhysRevD.77.092002 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Measurements of e+e- -> K+K-eta, K+K-pi0 and KsK+pi- Cross Sections Using Initial State Radiation Events </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/?searchtype=author&query=BaBar+Collaboration"> BaBar Collaboration</a>, <a href="/search/?searchtype=author&query=Aubert%2C+B">B.

From the Dalitz plot analysis of the KsK+pi- final state, moduli and relative phase of the isoscalar and the isovector components of the e+e- -> K K*(892) cross section are determined. Parameters of phi and rho recurrences are also measured, using a global fitting procedure which exploits the interconnection among amplitudes, moduli and phases of the e+e- -> KsK+pi-, K+K-pi0, phi eta final states.

We tag events by the presence of a hard photon in the detector, then reconstruct mu+mu- and several exclusive hadronic final states. The invariant mass of the final state determines an effective collision center of mass energy at which these measurements can be compared with results from direct e+e- annihilation process. The first results on e+e- --> 2h+2h-, where h=pi,K and on e+e- --> J/psi, obtained with a sample of 89.3/fb, are presented. Measurements of inclusive eta, pi+, K+ and p/anti-p production cross sections below the Y(4S) resonance are also presented. These measurements have nearly complete momentum coverage and precision comparable to the best measurements at higher energies. They therefore allow for precise tests of QCD predictions and fragmentation models at 10.54 GeV and of their scaling properties. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('hep-ex/0406017v1-abstract-full').style.display = 'none'; document.getElementById('hep-ex/0406017v1-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> 6 June, 2004; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> June 2004. </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 with 8 Encapsulated PostScript figures.
