This new detector, scheduled to be in operation from Run 4, will explore the small Bjorken-$x$ physics region in an unprecedented way. In this region the gluon saturation phenomenon is expected to be dominant. Combined with the rest of the ALICE subdetectors, including the zero degree calorimenters, FoCal will serve to reconstruct in a model-independent way the measured photoproduction cross sections for vectors mesons in a wide range of photon-target energies, down to $x$ values of about $7\times 10^{-6}$ and $2\times 10^{-6}$ in ultra-peripheral photon--proton and photon--lead collisions, respectively. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2211.16107v1-abstract-full').style.display = 'none'; document.getElementById('2211.16107v1-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 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">24 pages, 9 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/2207.10261">arXiv:2207.10261</a> <span> [<a href="https://arxiv.org/pdf/2207.10261">pdf</a>, <a href="https://arxiv.org/format/2207.10261">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 - 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/10.1016/j.nima.2023.168276">10.1016/j.nima.2023.168276 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Search for $e\to蟿$ Charged Lepton Flavor Violation at the EIC with the ECCE Detector </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ph?searchtype=author&query=Zhang%2C+J+-">J. -L.

In contrast to the $e \leftrightarrow 渭$ CLFV transition for which very stringent limits exist, there is still a relatively large discovery space for the $e \to 蟿$ CLFV transition, potentially to be explored by the EIC. With the latest detector design of ECCE (EIC Comprehensive Chromodynamics Experiment) and projected integral luminosity of the EIC, we find the $蟿$-leptons created in the DIS process $ep\to 蟿X$ are expected to be identified with high efficiency. A first ECCE simulation study, restricted to the 3-prong $蟿$-decay mode and with limited statistics for the Standard Model backgrounds, estimates that the EIC will be able to improve the current exclusion limit on $e\to 蟿$ CLFV by an order of magnitude. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2207.10261v1-abstract-full').style.display = 'none'; document.getElementById('2207.10261v1-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> 20 July, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 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 pages, 8 figures, to be submitted to NIM</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2009.03838">arXiv:2009.03838</a> <span> [<a href="https://arxiv.org/pdf/2009.03838">pdf</a>, <a href="https://arxiv.org/format/2009.03838">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 - Phenomenology">hep-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="Nuclear Experiment">nucl-ex</span> </div> </div> <p class="title is-5 mathjax"> New opportunities at the photon energy frontier </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ph?searchtype=author&query=Adam%2C+J">Jaroslav Adam</a>, <a href="/search/hep-ph?searchtype=author&query=Aidala%2C+C">Christine Aidala</a>, <a href="/search/hep-ph?searchtype=author&query=Angerami%2C+A">Aaron Angerami</a>, <a href="/search/hep-ph?searchtype=author&query=Audurier%2C+B">Benjamin Audurier</a>, <a href="/search/hep-ph?searchtype=author&query=Bertulani%2C+C">Carlos Bertulani</a>, <a href="/search/hep-ph?searchtype=author&query=Bierlich%2C+C">Christian Bierlich</a>, <a href="/search/hep-ph?searchtype=author&query=Blok%2C+B">Boris Blok</a>, <a href="/search/hep-ph?searchtype=author&query=Brandenburg%2C+J+D">James Daniel Brandenburg</a>, <a href="/search/hep-ph?searchtype=author&query=Brodsky%2C+S">Stanley Brodsky</a>, <a href="/search/hep-ph?searchtype=author&query=Bylinkin%2C+A">Aleksandr Bylinkin</a>, <a href="/search/hep-ph?searchtype=author&query=Roman%2C+V+C">Veronica Canoa Roman</a>, <a href="/search/hep-ph?searchtype=author&query=Celiberto%2C+F+G">Francesco Giovanni Celiberto</a>, <a href="/search/hep-ph?searchtype=author&query=Cepila%2C+J">Jan Cepila</a>, <a href="/search/hep-ph?searchtype=author&query=Chachamis%2C+G">Grigorios Chachamis</a>, <a href="/search/hep-ph?searchtype=author&query=Cole%2C+B">Brian Cole</a>, <a href="/search/hep-ph?searchtype=author&query=Contreras%2C+G">Guillermo Contreras</a>, <a href="/search/hep-ph?searchtype=author&query=d%27Enterria%2C+D">David d'Enterria</a>, <a href="/search/hep-ph?searchtype=author&query=Dumitru%2C+A">Adrian Dumitru</a>, <a href="/search/hep-ph?searchtype=author&query=T%C3%A9llez%2C+A+F">Arturo Fern谩ndez T茅llez</a>, <a href="/search/hep-ph?searchtype=author&query=Frankfurt%2C+L">Leonid Frankfurt</a>, <a href="/search/hep-ph?searchtype=author&query=Ducati%2C+M+B+G">Maria Beatriz Gay Ducati</a>, <a href="/search/hep-ph?searchtype=author&query=Geurts%2C+F">Frank Geurts</a>, <a href="/search/hep-ph?searchtype=author&query=da+Silveira%2C+G+G">Gustavo Gil da Silveira</a>, <a href="/search/hep-ph?searchtype=author&query=Giuli%2C+F">Francesco Giuli</a>, <a href="/search/hep-ph?searchtype=author&query=Goncalves%2C+V+P">Victor P.

The dependence of the NNLO predictions and of the resulting value of $伪_s(M_Z)$ at the $Z$-boson mass $m_Z$ are studied as a function of the choice of the renormalisation and factorisation scales. Using inclusive jet and dijet data together, the strong coupling constant is determined to be $伪_s(M_Z)=0.1166\,(19)_{\rm exp}\,(24)_{\rm th}$. Complementary, $伪_s(M_Z)$ is determined together with parton distribution functions of the proton (PDFs) from jet and inclusive DIS data measured by the H1 experiment. The value $伪_s(M_Z)=0.1147\,(25)_{\rm tot}$ obtained is consistent with the determination from jet data alone. The impact of the jet data on the PDFs is studied. The running of the strong coupling is tested at different values of the renormalisation scale and the results are found to be in agreement with expectations. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1709.07251v2-abstract-full').style.display = 'none'; document.getElementById('1709.07251v2-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> 16 June, 2021; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 21 September, 2017; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 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">45 pages, 17 figures, with changes discussed in an erratum submitted to EPJ C</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> DESY17-137 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1506.04285">arXiv:1506.04285</a> <span> [<a href="https://arxiv.org/pdf/1506.04285">pdf</a>, <a href="https://arxiv.org/format/1506.04285">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 - 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/10.1016/j.nuclphysb.2015.12.009">10.1016/j.nuclphysb.2015.12.009 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Two components in charged particle production in heavy-ion collisions </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ph?searchtype=author&query=Bylinkin%2C+A+A">A.

It is seen that the slope of low-$p_T$ distributions is changing with energy. This effect impacts on the energy dependence of average transverse momenta, which behaves approximately as $s^{0.06}$ that is similar to the previously observed behavior for $螞^0$-baryon spectra. In addition, the available data on $螞_c$ production from LHCb at $\sqrt{s}= 7$ TeV were also studied. The estimated average $<p_T>$ is bigger than this value for protons proportionally to masses. The preliminary dependence of hadron average transverse momenta on their masses at LHC energy is presented. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1501.07706v1-abstract-full').style.display = 'none'; document.getElementById('1501.07706v1-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> 30 January, 2015; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2015. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1501.05235">arXiv:1501.05235</a> <span> [<a href="https://arxiv.org/pdf/1501.05235">pdf</a>, <a href="https://arxiv.org/format/1501.05235">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 - 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/10.1140/epjc/s10052-015-3392-y">10.1140/epjc/s10052-015-3392-y <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Predictions on the transverse momentum spectra for charged particle production at LHC-energies from a two component model </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ph?searchtype=author&query=Bylinkin%2C+A">Alexander Bylinkin</a>, <a href="/search/hep-ph?searchtype=author&query=Chernyavskaya%2C+N">Nadezda Chernyavskaya</a>, <a href="/search/hep-ph?searchtype=author&query=Rostovtsev%2C+A">Andrei Rostovtsev</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="1501.05235v1-abstract-short" style="display: inline;"> Transverse momentum spectra, $d^2蟽/(d畏dp_T^2)$, of charged hadron production in $pp$-collisions are considered in terms of a recently introduced two component model.

Recently, the H1 Collaboration has discovered that the relative strength of these two components in Deep Inelastic Scattering depends drastically upon the global structure of the event - namely, the exponential component is absent in the diffractive events characterized by a rapidity gap. We discuss the possible origin of this effect, and speculate that it is linked to confinement. Specifically, we argue that the thermal component is due to the effective event horizon introduced by the confining string, in analogy to the Hawking-Unruh effect. In diffractive events, the $t$-channel exchange is color-singlet and there is no fragmenting string -- so the thermal component is absent. The slope of the soft component of the hadron spectrum in this picture is determined by the saturation momentum that drives the deceleration in the color field, and thus the Hawking-Unruh temperature. We analyze the data on non-diffractive $pp$ collisions and find that the slope of the thermal component of the hadron spectrum is indeed proportional to the saturation momentum. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1407.4087v1-abstract-full').style.display = 'none'; document.getElementById('1407.4087v1-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 July, 2014; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2014. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1405.3055">arXiv:1405.3055</a> <span> [<a href="https://arxiv.org/pdf/1405.3055">pdf</a>, <a href="https://arxiv.org/format/1405.3055">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 - Phenomenology">hep-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Nuclear Experiment">nucl-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Nuclear Theory">nucl-th</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.90.018201">10.1103/PhysRevC.90.018201 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Hydrodynamic extension of the two component model for hadroproduction in heavy-ion collisions </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ph?searchtype=author&query=Bylinkin%2C+A+A">A.

The observed regularities might be explained by the formation of QGP during the collision. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1405.3055v1-abstract-full').style.display = 'none'; document.getElementById('1405.3055v1-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> 13 May, 2014; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2014. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.
