The ATLAS trigger system / De Maria, Antonio (Nanjing University (CN)) /ATLAS Collaboration
The ATLAS experiment in the LHC Run 3 uses a two-level trigger system to select events of interest to reduce the 40 MHz bunch crossing rate to a recorded rate of up to 3 kHz of fully-built physics events. The trigger system is composed of a hardware based Level-1 trigger and a software based High Level Trigger. [...]

Estimation of backgrounds from jets misidentified as tau leptons using the Universal Fake Factor method with the ATLAS detector / Morodei, Federico (Sapienza Universita e INFN, Roma I (IT)) /ATLAS Collaboration
Physical processes with one or more τ-lepton in the final state play an important role in several analyses of the ATLAS experiment physics program. The usage of hadronic channels, in which τ-leptons decay into one or more pions, enables to exploit the large statistics associated with hadronic τ-lepton decays, but also requires a precise estimate of a sizable background of hadronic jets mis-reconstructed as fake τ-leptons. [...]

Measurement of multi-jets and boson plus jets production with ATLAS / Delagrange, Line (Centre National de la Recherche Scientifique (FR)) /ATLAS Collaboration
Production of multiple jets or bosons plus jets at the LHC offers an unprecedented opportunity to study QCD in the high-energy regime. As experimental precision advances, thorough QCD studies are enabled by measurements of a variety of different observables, including different topological configurations between vector bosons and jets, jet substructure observables, and heavy-flavor jets.

Measurement and related interpretations of $W^{\pm}Z$ cross-sections in pp collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector / Boudet, Leo (Centre National de la Recherche Scientifique (FR)) /ATLAS Collaboration
Measurements of integrated and differential cross-sections for $W^{\pm}Z$ production in proton–proton collisions are presented. The data collected by the ATLAS detector at the Large Hadron Collider from 2015 to 2018 at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV are used, corresponding to an integrated luminosity of 140 fb$^{-1}$.

Search for CP violating effects in HWW vertex in the WH production channel in 13 TeV pp collisions with the ATLAS detector / Kholodenko, Marina (Laboratory of Instrumentation and Experimental Particle Physics (PT)) /ATLAS Collaboration
The Standard Model (SM) predicts the Higgs boson to be a CP-even (scalar) particle. Any deviation from a purely CP-even interaction of the Higgs boson with other SM particles would indicate physics beyond the SM. [...]

The phase-1 upgrade of the ATLAS level-1 calorimeter trigger / Gugel, Ralf (Johannes Gutenberg Universitaet Mainz (DE)) ; ATLAS Collaboration /ATLAS Collaboration
The ATLAS level-1 calorimeter trigger is a custom-built hardware system that identifies events containing calorimeter-based physics objects, including electrons, photons, taus, jets, and total and missing transverse energy. In Run 3, L1Calo has been upgraded to process higher granularity input data. [...]

Searches for heavy resonances (including new scalars & BSM Higgs decays) / Bahmani, Marzieh (Humboldt University of Berlin (DE)) /ATLAS Collaboration
Though the Standard Model (SM) of particle physics has been a very successful theory in explaining a wide range of measurements, there are still many questions left unanswered such as incorporation of gravity into SM, neutrino masses, matter-antimatter asymmetry, supersymmetry, or existence of dark matter candidates. One of the possible solutions to address these challenges is the extension of the SM with the presence of additional, heavy BSM particles; including scalar (H/S), pseudoscalar (A), or charged (H+-/H++--) BSM Higgs bosons. [...]

Searches for new phenomena in hadronic final states using the ATLAS detector / Barakat, Marawan (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
Many theories beyond the Standard Model predict new phenomena giving rise to multijet final states. These jets could originate from the decay of a heavy resonance into SM quarks or gluons, or from more complicated decay chains involving additional resonances that decay e.g. [...]

Searches for strong production of supersymmetric particles / Yuan, Jiarong (Chinese Academy of Sciences (CN)) /ATLAS Collaboration
Supersymmetry (SUSY) provides elegant solutions to several problems in the Standard Model, and searches for SUSY particles are an important component of the LHC physics program. Naturalness arguments favour supersymmetric partners of the gluons and third-generation quarks with masses light enough to be produced at the LHC. [...]

Top quark (including associated production) cross section measurements with the ATLAS detector / Rej, Amartya (Technische Universitaet Dortmund (DE)) /ATLAS Collaboration
The exceptionally large dataset collected by the ATLAS detector at the highest proton-proton collision energies provided by the LHC enables precision testing of theoretical predictions using an extensive sample of top quark events. Recent measurements include total and differential top quark cross sections, as well as measurements of associated top quark production. [...]
