ISR and FSR of Dark Photons / Reimitz, Peter (speaker) (University of Sao Paulo)
We study the relevance of Initial- and Final-State radiation in QCD processes at the LHC as a production mechanism for dark photons. We implement dark photon splitting functions to quarks into the Monte-Carlo Generator Herwig and add it to the forward and backward evolution of the parton shower in LHC events. [...]

Looking forward to photon-coupled sub-GeV long-lived particles / Jodlowski, Krzysztof (speaker)
Many Dark Sector models contain photon-coupled long-lived particles. An outstanding example is an axion-like particle decaying into two photons. [...]

The radiative return at phi- and B-factories: FSR at next-to-leading order / Czyz, Henryk (Silesia U.) ; Grzelinska, Agnieszka (Silesia U.) ; Kuhn, Johann H. (Karlsruhe U., TTP) ; Rodrigo, German (CERN)
The measurement of the pion form factor and, more generally, of the cross section for electron--positron annihilation into hadrons through the radiative return has become an important task for high luminosity colliders such as the $\Phi$- or $B$-meson factories. For detailed understanding and analysis of this reaction, the construction of a Monte Carlo program, PHOKHARA, has been undertaken. [...]

Particle production as a function of underlying-event activity and very forward energy with ALICE / Fan, Feng (Hua-Zhong Normal U.) /ALICE Collaboration
Measurements of charged-particle production in pp and p-Pb collisions at $\sqrt{s}_{\rm NN}=5.02$ TeV in the toward, away and transverse regions are discussed. These three regions are defined event by event relative to the track with the largest transverse momentum ($p_{\rm T}^{\rm trig}$). [...]

NLO QCD+EW predictions for $2\ell2\nu$ diboson signatures at the LHC / Kallweit, S. (CERN) ; Lindert, J.M. (Durham U., IPPP) ; Pozzorini, S. (Zurich U.) ; Schönherr, M. (Zurich U.)
We present next-to-leading order (NLO) calculations including QCD and electroweak (EW) corrections for $2\ell2\nu$ diboson signatures with two opposite-charge leptons and two neutrinos. Specifically, we study the processes $pp\to e^+ \mu^- \nu_{e}\bar\nu_{\mu}$ and $pp\to e^+ e^-\nu\bar\nu$, including all relevant off-shell diboson channels, $W^+W^-$, $ZZ$, $\gamma Z$, as well as non-resonant contributions.

Electroweak corrections at the LHC: the contribution of photons / Pagani, Davide (Munich, Tech. U.)
In this talk I review the photon contribution to the electroweak corrections for some of the most relevant processes at the LHC, namely, the Drell-Yan, $VV$, $t \bar{t}$ and dijet production. In the discussion I focus on two dominant effects: photon radiation from final-state light particles and the impact of the photon PDF..

Rapidity evolution of collision geometry from the improved TRENTo-3D model / Ke, Weiyao (speaker) (University of California, Berkeley; Lawrence-Berkeley National )
We propose a new parameterization of the three-dimensional initial condition for the application of the hydrodynamic model to relativistic heavy-ion collisions. In particular, we implement different average-energy production scaling behaviors for different rapidity regions in this proposed ansatz. [...]

Searches for new physics with the FASER Experiment / MacDonald, Jack Cameron (Mainz U.) /FASER Collaboration
FASER, the ForwArd Search ExpeRiment, is an LHC experiment located 480 m downstream of the ATLAS interaction point, along the beam collision axis. FASER was designed, constructed, installed, and commissioned during 2019-2022 and has been taking physics data since the start of LHC Run 3 in July 2022. [...]
