Convolutional Neural Networks for pile-up suppression in the ATLAS Global Trigger / Clarke Hall, Noah (University of London (GB)) ; Konstantinidis, Nikolaos (University of London (GB)) ; Kimura, Naoki (University of London (GB)) ; Martynwood, Alex Christopher (University of London (GB)) /ATLAS Collaboration
We describe a pile-up suppression algorithm for the ATLAS Global Trigger, using a convolutional neural network (CNN) architecture. The CNN operates on cell towers and exploits both shower topology and $E_T$ to correct for the contribution of pile-up. [...]

ATLAS Inner Detector Operational Experience at the Large Hadron Collider at CERN / Akiyama, Daiya (Waseda University (JP)) ; ATLAS Pixel Collaboration ; ATLAS SCT Collaboration /ATLAS Collaboration
The tracking and vertexing performance of the ATLAS detector relies critically on the silicon and gaseous tracking subsystems that form the ATLAS Inner Detector. They have been operated successfully with high performance in LHC since Run 1 (2010) up to the current date. [...]

BSM H(125) aspects and searches for new scalar bosons / Skorda, Eleni (University of Birmingham (GB)) /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 BSM particles, including scalar, pseudoscalar, or charged BSM Higgs bosons; as well as the considering of rare Higgs decays. [...]

A High-Dimensional, Unbinned Standard Model Measurement with the ATLAS Experiment / Pettee, Mariel (Lawrence Berkeley National Lab. (US)) /ATLAS Collaboration
Traditional approaches to precise Standard Model (SM) measurements of fundamental particles at the LHC generally restrict the format of these results to just one or two properties at a time in predetermined histogram bins. The ATLAS Experiment recently published such a measurement in a notable new format for LHC experiments: high-dimensional and unbinned datasets that can be used for a wide range of scientific applications.

Searches for Higgs boson pair production in the ATLAS experiment / Ferrari, Arnaud (Uppsala University (SE)) /ATLAS Collaboration
In the Standard Model, the ground state of the Higgs field is not found at zero but instead corresponds to one of the degenerate solutions minimising the Higgs potential. In turn, this spontaneous electroweak symmetry breaking provides a mechanism for the mass generation of nearly all fundamental particles. [...]

Overview of ATLAS muon detectors: status and performance / Izumiyama, Shota (Nagoya University (JP)) ; ATLAS Collaboration /ATLAS Collaboration
The ATLAS Muon Spectrometer, the largest muon system ever built at colliders, now comprises both legacy gaseous detectors—Monitored Drift Tubes (MDT), Thin Gap Chambers (TGC), and Resistive Plate Chambers (RPC)—which have been in operation for over 15 years, as well as newer technologies like Micromegas and small-strip TGCs in the NSW. These new systems are now in stable operation following an extensive phase of construction and commissioning, providing enhanced muon tracking and trigger capabilities. [...]

ATLAS Tile calorimeter: Performance and upgrade for HL-LHC conditions / Tropina, Anastasiia (Joint Institute for Nuclear Research (RU)) /ATLAS Collaboration
The Tile Calorimeter (TileCal) is the hadronic calorimeter covering the central region of the ATLAS experiment, which measures energies in range from about 30 MeV to about 2 TeV. TileCal is a sampling calorimeter with steel as absorber and scintillators as active medium. [...]

GELATO: A Generic Event-Level Anomalous Trigger Option for ATLAS / Addepalli, Sagar (SLAC National Accelerator Laboratory (US)) /ATLAS Collaboration
The absence of beyond-Standard-Model physics discoveries at the LHC suggests that new physics may evade conventional trigger strategies. The existing ATLAS triggers are required to control data collection rates with high energy thresholds and target signal topologies specific to only certain models. [...]

Searches for supersymmetry in non-minimal models with ATLAS / Nguyen, Hoang Dai Nghia (Universite de Montreal (CA)) /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. With increasing mass bounds on MSSM scenarios other non-minimal variations of supersymmetry become increasingly interesting. [...]
