Quark-Gluon Constituent-Based Jet Taggers for the HL-LHC / Castillo, Florencia Luciana (Centre National de la Recherche Scientifique (FR)) /ATLAS Collaboration
Jet constituents provide a more detailed description of the radiation pattern within a jet compared to observables summarizing global jet properties. In Run 2 analyses at the LHC using the ATLAS detector, transformer-based taggers leveraging low-level variables outperformed traditional approaches based on high-level variables and conventional neural networks in distinguishing quark- and gluon-initiated jets.

Study of soft QCD phenomena and double parton interactions with ATLAS / Todorova, Sarka (Charles University (CZ)) /ATLAS Collaboration
Despite the success of perturbative QCD predictions in the high-energy regime, QCD itself remains mysterious at its nominal non-perturbative QCD scale. The LHC offers rich opportunities to probe the core of QCD related questions, by studying minibias events, double parton interactions, small-x and diffractive processes, as well as correlations in hadronization processes.

Heavy flavour production and decay in ATLAS / Barton, Adam Edward (Lancaster University (GB)) /ATLAS Collaboration
This talk will present the recent results from ATLAS experiments on open-charm meson production measurements and various studies of b hadron decays, including the most precise measurement of the $B^0$ lifetime..

The LHC as Lepton-Proton Collider: Search for the Resonant Production of Leptoquarks / Buchin, Daniel Alexander (Max Planck Society (DE)) /ATLAS Collaboration
Searches for leptoquarks are a key component of the LHC program probing physics beyond the Standard Model. These hypothetical particles couple to a lepton and a quark and are predicted by many extensions of the Standard Model such as Grand Unified Theories. [...]

Search for rare processes and lepton-flavor-violating decays of Higgs boson at the ATLAS experiment / Zakareishvili, Tamar (Univ. of Valencia and CSIC (ES)) /ATLAS Collaboration
The Standard Model predicts several rare Higgs boson processes, including decays into a Z boson and a photon, a low-mass lepton pair and a photon, or a meson and a photon. Observing these rare decays would offer new and complementary insights into the Higgs boson's coupling structure beyond the more commonly studied channels. [...]

Status and testing of the MDT Trigger Processor for the ATLAS Level-0 Muon Trigger at HL-LHC / Longarini, Iacopo (University of California Irvine (US)) /ATLAS Collaboration
The Monitored Drift Tube Trigger Processor (MDT-TP) will improve the rate capabilities of the first-level muon (L0 Muon) trigger of the ATLAS Experiment during the operation of the HL-LHC. The information of the trigger candidate, obtained by other muon trigger subsystems, will be combined with the precision of the MDT chambers in order to improve the resolution on the muon momentum measurement, while limiting the trigger rate to an acceptable level in the high-pileup environment of HL-LHC.

Performance, Calibration and Optics Robustness of the ATLAS Tile Calorimeter / Zenis, Tibor (Comenius University (SK)) /ATLAS Collaboration
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment, operating at the Large Hadron Collider (LHC) at CERN. TileCal is made of steel as absorber and plastic scintillators as active medium. [...]

Performance and upgrade of the ATLAS Hadronic Tile Calorimeter / Faltova, Jana (Charles University (CZ)) /ATLAS Collaboration
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment, with steel as absorber and plastic scintillators as active medium. The scintillators are read-out by the wavelength shifting fibres coupled to the photomultiplier tubes (PMTs). [...]

Fast Rejection of Pile-Up Jets in the ATLAS HLT using the DIPz + MLPL Approach / Aboelela, Mohammed (Southern Methodist University (US)) /ATLAS Collaboration
DIPZ is a machine learning algorithm aiming to re-purpose the Deep Impact Parameter Sets (DIPS) jet-flavour taggers to instead regress the jet’s origin vertex position along the beam-line axis. Deployed at the ATLAS High Level Trigger (HLT), the DIPZ labels of each jet in an event are then used in an HLT jet algorithm to construct an event-wide likelihood-based discriminant variable (MLPL), which is used to select events compatible with targeted multi-jet signature selection.
