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. [...]

Enhancing the ATLAS Level-1 endcap muon trigger with New Small Wheel integration in Run 3 / Saito, Tomoyuki (University of Tokyo (JP)) ; ATLAS Collaboration /ATLAS Collaboration
The Level-1 muon endcap trigger in the ATLAS experiment utilises signals from the Thin Gap Chambers (TGCs) located in the outer muon stations. A significant challenge for this system has been the high background rate caused by particles not originating at the interaction point, which increased the Level-1 trigger rate. [...]

Top quark mass and properties with the ATLAS detector / Moskalets, Tetiana (Southern Methodist University (US)) /ATLAS Collaboration
The top-quark mass is one of the key fundamental parameters of the Standard Model that must be determined experimentally. Its value has an important effect on many precision measurements and tests of the Standard Model. [...]

Operational Experience and Performance with the ATLAS Pixel detector at the Large Hadron Collider at CERN / Rodriguez Bosca, Sergi (CERN) /ATLAS Collaboration
The tracking performance of the ATLAS detector relies critically on its 4-layer Pixel Detector, with a sensitive area of ~1.9 m2 and 92 million pixels. Its original part, consisting in 3 layers of planar pixel sensor is continuously operating since the start of LHC collisions in 2008, while Its innermost layer, the Insertable B Layer (IBL) at about 3 cm from the beam line, was installed in 2015 before the start of LHC Run2 and consists of both planar and 3D pixel sensors, with FE-I4 readout frontends at 130nm CMOS technology.

New techniques for reconstructing and calibrating hadronic objects with ATLAS / Morancho Tarda, Arnau (University of Copenhagen (DK)) /ATLAS Collaboration
The precision and reach of physics analyses at the LHC is often tied to the performance of hadronic object reconstruction & calibration, with any incremental gains in understanding & reduced uncertainties being impactful on ATLAS results. Recent refinements to the reconstruction and calibration procedures for jets & missing energy by the ATLAS collaboration has resulted in reduced uncertainties, improved pileup stability and overall performance gains.

Measurements of Drell-Yan processes with ATLAS / ATLAS Collaboration /ATLAS Collaboration
Precision measurements of Drell-Yan processes, including on-shell and off-shell W- and Z-boson production, offer key input to improve the understanding of QCD and the accuracy of PDFs. In addition, Drell-Yan measurements are instrumental for precision measurements of fundamental electroweak parameters, such as W boson mass measurement. [...]
