NA65(DsTau): Study of tau neutrino production in p-A interactions / Yuksel, Emin (Middle East Tech. U., Ankara) /DsTau (NA65) Collaboration
The DsTau (NA65) experiment at CERN was proposed to measure an inclusive differential cross-section of $D_{s}$ production, and its decay branching ratios in p-A interactions. The DsTau detector is based on the nuclear emulsion technique providing an excellent spatial resolution for detecting short-lived particles like charmed hadrons. [...]

First study of initial gluonic fluctuations using UPCs with ALICE / Grund, David (Prague, Tech. U.) /ALICE Collaboration
Incoherent photoproduction is sensitive to fluctuations in the gluon structure of the target. Thus, the photoproduction measurement off colliding hadrons sheds light on QCD at high energies and provides important constraints on the initial conditions used in hydrodynamical models of heavy-ion collisions.

xFitter Updates: Probing Z Boson Couplings with Forward-Backward Asymmetry / Zenaiev, Oleksandr (Hamburg U.) /xFitter developers’ Team Collaboration
We present recent updates in the xFitter software framework for global fits of parton distribution functions in high-energy physics. Our focus is on investigating the sensitivity to Z boson couplings using the forward-backward asymmetry in Drell-Yan production. [...]

Latest results for searches of exotic decays with NA62 in beam-dump mode / Kleimenova, Alina (LPHE, Lausanne) /NA62 Collaboration
The NA62 experiment at CERN took data in 2016–2018 with the main goal of measuring the $K^+ \rightarrow \pi^+ \nu \bar{\nu}$ decay. In this talk we report on the search for visible decays of exotic mediators from data taken in "beam-dump" mode with the NA62 experiment. [...]

Azimuthal anisotropy from quantum interference in $\rho^0$ photoproduction in ultra-peripheral collisions with ALICE / Riffero, Andrea Giovanni (Turin U. ; INFN, Turin) /ALICE Collaboration
Ultra-peripheral heavy-ion collisions (UPCs) occur when the impact parameter of the collision is greater than the sum of the radii of the colliding nuclei. UPCs allow one to study photon-induced reactions, such as the photoproduction of a vector meson, which is a well-established tool to probe the gluon structure of the colliding nuclei. [...]

Measurement of single W and Z boson properties in the Forward Region / Abdelmotteleb, Ahmed Sameh Wagih (Warwick U.) /LHCb Collaboration
The LHCb experiment covers the forward region of proton-proton collisions, and it can improve the current electroweak landscape by studying the production of electroweak bosons in this phase space complementary to ATLAS and CMS. The precision measurements of the properties of single W and Z boson at LHCb could not only provide stringent test of the Standard Model, but also are essential inputs for the PDF global fitting.

CMS jet measurements and constraints on PDFs and $\alpha_\text{s}$ / Savoiu, Daniel (Hamburg U., Inst. Exp. Phys. II) /CMS Collaboration
A selection of recent jet measurements in proton-proton collisionsfrom the CMS Collaboration at the CERN LHC is presented.Several experimental results targeting jet production are summarized, includingdifferential measurements of the inclusive jet cross section at center-of-massenergies of $\sqrt{s}$ = 13 TeV and 5.02 TeV, and of the dijet cross sectionat $\sqrt{s}$ = 13 TeV.The measurements are compared to state-of-the-art theoretical predictionsat next-to-next-to-leading-order accuracy in perturbative QCD, and the strong couplingconstant $\alpha_\text{s}(m_\text{Z})$ is extracted simultaneously with the parton distribution functions (PDFs)of the proton at 13 TeV.A further experimental handle on $\alpha_\text{s}(m_\text{Z})$ is provided by a measurement of jetazimuthal correlations.Finally, a novel measurement of the energy-energy correlators inside jets is outlined. These providean additional way of determining $\alpha_\text{s}(m_\text{Z})$ while also constituting useful observables forprobing phase spaces dominated by nonperturbative processes like hadronization and haveapplications in the context of Monte Carlo event generator tuning..

Neutrinos at the LHC - Results from FASER / Atkinson, Jeremy (U. Bern, AEC) /FASER Collaboration
The goal of FASER, the ForwArd Search ExpeRiment, at the CERN LHC, is to investigate light, weakly-interacting particles. Aligned with the collision axis line-of-sight of the ATLAS interaction point, it is located 480 m downstream, and covers the previously unexplored pseudorapidity range of 𝜂 > 8.8. [...]

Recent results on open heavy flavor production ($pp$, $p$Pb, PbPb) from LHCb / Gu, Chenxi (LLR, Palaiseau) /LHCb Collaboration
Heavy quarks are produced in the early stages of heavy ion collisions due to their large mass, and subsequently traverse the entire QCD medium evolution. Open heavy flavors provide profound insights into the transport properties of the medium and the process by which quarks neutralize their color charge to form hadrons. [...]

Higgs self-coupling at the FCC-hh / Gallo, Elisabetta (DESY ; Hamburg U.) ; Grojean, Christophe (DESY) ; Mastrapasqua, Paola (Louvain U., CP3) ; Selvaggi, Michele (CERN) ; Stapf, Birgit (Hamburg U.) ; Tackmann, Kerstin (DESY ; Hamburg U.) ; Taliercio, Angela (Northwestern U.)
The Higgs self-coupling 𝜆 governs the shape of the Higgs potential and its precise determination is one of the main goals at future colliders. Here we present a new study based on fast simulations at the FCC-hh, assuming √𝑠 = 100 TeV and an integrated luminosity of 30 ab$^{−1}$. [...]
