LHC as an Axion-Photon Collider / Barbosa, Sergio (ABC Federal U.) ; Coelho, Matheus (ABC Federal U.) ; Fichet, Sylvain (ABC Federal U.) ; da Silveira, Gustavo Gil (Unlisted, BR ; CERN) ; Machado, Magno (Rio Grande do Sul U., Porto Alegre (main))
Assuming the existence of an axion-like particle (ALP), beams of relativistic particles emit fluxes of quasi-real ALPs, analogous to the photon fluxes described by Weizsäcker-Williams-type approximations. Consequently, ALP-ALP and ALP-photon collisions can occur at the LHC. [...]

Yield and performance validation of the Monolithic Stitched Sensor (MOSS), the first wafer-scale prototype for the ALICE ITS3 upgrade / Menzel, Marius Wilm (CERN ; U. Heidelberg (main))
The ALICE Inner Tracking System upgrade (ITS3) will employ stitched, wafer-scale Monolithic Active Pixel Sensors (MAPS) for the first time in high-energy physics, achieving a material budget of only 0.09$\,$%$\,$X$\mathrm{_{0}}$ per layer. [...]

Magnusian: Relating the Eikonal Phase, the On-Shell Action, and the Scattering Generator / Kim, Jung-Wook (CERN ; Potsdam, Max Planck Inst.) ; Patil, Raj (Potsdam, Max Planck Inst. ; Humboldt U., Berlin) ; Scheopner, Trevor (Potsdam, Max Planck Inst.) ; Steinhoff, Jan (Potsdam, Max Planck Inst.)
Two fundamentally distinct quantities are both called "eikonal" in present amplitudes literature. [...]

The size of the quark-gluon plasma in ultracentral collisions: impact of initial density fluctuations on the average transverse momentum / Zhou, Fabian (U. Heidelberg, ITP) ; Giacalone, Giuliano (CERN) ; Ollitrault, Jean-Yves (IPhT, Saclay)
Recent experiments have shown that the mean transverse momentum $\langle p_T\rangle$ of outgoing particles increases as a function of the particle multiplicity in ultracentral nucleus-nucleus collisions at collider energies. [...]

Isospin-violating vacuum polarization in the muon (g − 2) with SU(3) flavour symmetry from lattice QCD / Erb, Dominik (U. Mainz, PRISMA ; Mainz U., Inst. Kernphys.) ; Gérardin, Antoine (Marseille, CPT) ; Meyer, Harvey B. (U. Mainz, PRISMA ; Helmholtz Inst., Mainz ; Mainz U., Inst. Kernphys. ; CERN) ; Parrino, Julian (Regensburg U.) ; Biloshytskyi, Volodymyr (Mainz U., Inst. Kernphys. ; Marseille, CPT) ; Pascalutsa, Vladimir (Mainz U., Inst. Kernphys.)
We compute the isospin-violating part $a_μ^{\text{HVP}, 38}$ of the hadronic-vacuum-polarization (HVP) contribution to the muon $(g-2)$ in lattice QCD at the SU$(3)_{\rm f}$-symmetric point where $M_π=M_K\simeq 416$ MeV. All diagrams involving internal photons are evaluated in coordinate space, employing a Pauli-Villars-regulated photon propagator with a cutoff scale $Λ$ well below the lattice cutoff. [...]

We consider the transverse momentum ($q_T$) distribution of neutral charged bosons at hadron colliders. [...]

Deep Learning for Primary Vertex Identification in the ATLAS Experiment / Garg, Rocky Bala (Stanford University (US)) /ATLAS Collaboration
The exponential time scaling of traditional primary vertex reconstruction algorithms, such as the Adaptive Multi-Vertex Finder (AMVF), raises significant performance concerns for future high-pileup environments, particularly with the upcoming High Luminosity upgrade to the Large Hadron Collider. In this talk, we introduce PV-Finder, a deep learning-based approach that leverages reconstructed track parameters to directly predict primary vertex positions and track-to-vertex associations. [...]

Search for long-lived particles using displaced vertices with low-momentum tracks in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
A search for long-lived particles using final states including a displaced vertex with low-momentum tracks, large missing transverse momentum, and a jet from initial-state radiation is presented. [...]

An overview of the test station involved in the production of the LVPS Boards for the Phase II upgrade of the ATLAS Tile Calorimeter / Chabalala, Vongani Cyril (University of the Witwatersrand (ZA)) ; Pilusa, Thabo (University of the Witwatersrand (ZA)) ; Mosomane, Chuene Johannes (iThemba LABS, National Research Foundation (ZA)) ; Mckenzie, Ryan Peter (University of the Witwatersrand (ZA)) ; Mellado Garcia, Bruce (University of the Witwatersrand (ZA))
The Phase-II upgrade of the Tile Calorimeter (TileCal) in the ATLAS detector is a key step toward supporting upcoming high-energy physics research and preparing CERN for the High Luminosity Large Hadron Collider (HL-LHC). [...]
