 Small-Strip Thin Gap Chambers and electronics performance for the Muon Spectrometer Upgrade of the ATLAS Experiment / Naseri, Mohsen (Carleton University) /ATLAS Collaboration The largest phase-1 upgrade project for the ATLAS Muon System is the replacement of the present first station in the forward regions with the New Small Wheels (NSWs). The NSWs consist of two detector technologies: Micromegas (MM) and small-strip Thin-Gap Chamber (sTGC). [...] ATL-MUON-SLIDE-2020-287.- Geneva : CERN, 2020 - 22 p.

 Search for high mass resonance in di-jet and di-b-jet events using 139 fb-1 of pp collisions at √s=13 TeV with the ATLAS detector / Zhang, Dengfeng (Tsinghua University) /ATLAS Collaboration New resonances decaying into pairs of quarks or gluons appear in a variety of new physics models from simple gauge extensions of the standard model to Grand Unified Theories. The dijet final state at high transverse momentum can probe the highest energies reached in a collider experiment. [...] ATL-PHYS-SLIDE-2020-286.- Geneva : CERN, 2020 - 5 p.

 When jets MET SUSY: ATLAS Searches for Squarks and Gluinos / O'neill, Aaron Paul (University of Oxford, Particle Physics) /ATLAS Collaboration In many supersymmetric scenarios, heavy Beyond Standard Model particles would decay to multiple massive Standard Model bosons or top quarks. The subsequent decays of these Standard Model particles into leptons and/or jets may then occur with significant branching ratios and can populate the events recorded by the ATLAS detector.

 Electroweak probes in heavy-ion collisions with ATLAS / Kremer, Jakub Andrzej (Institut fuer Physik, Universitaet Mainz) /ATLAS Collaboration Electroweak bosons produced in lead-lead (Pb+Pb) collisions are an excellent tool to constrain initial-state effects which affect the rates of hard-scattering processes in nucleus-nucleus interactions. The production yields of massive electroweak bosons, observed via their leptonic decay channels, offer a high-precision test of the binary collision scaling expected in Pb+Pb and a way to quantify nuclear modifications of the parton distribution functions (PDFs).

 Search for new phenomena in mono-X final states using pp collision data collected in Run-2 by the ATLAS experiment at the LHC / Gonzalez Fernandez, Sergio (Institut de Fisica d'Altes Energies (IFAE), Barcelona Institute of Science and Technology, Barcelona, Spain) ; ATLAS Collaboration /ATLAS Collaboration Cosmological and astrophysical observation point to the existence of an exotic type of matter known as Dark Matter (DM) that accounts for about 27% of the total mass-energy of the Universe. If DM is realized in the form of weakly interacting massive particles (WIMPs) it could be produced at the LHC pp collider. [...] ATL-PHYS-SLIDE-2020-283.- Geneva : CERN, 2020 - 5 p.

 Search for resonances decaying to photon pairs in 139 $fb^{−1}$ of pp collisions at \$\sqrt{ / Wang, Yufeng (University of Science and Technology of China) /ATLAS Collaboration Since the discovery of the 125 GeV Higgs boson at the LHC, studies of the Higgs sector have become an important topic of the ATLAS physics program. There are many potential extensions of the Standard Model (SM) that predict new high-mass states decaying into two photons. [...] ATL-PHYS-SLIDE-2020-281.- Geneva : CERN, 2020 - 5 p.

 Search for Leptoquarks using the ATLAS detector / Okumura, Yasuyuki (International Center for Elementary Particle Physics and Department of Physics, The University of Tokyo) /ATLAS Collaboration Leptoquarks (LQ) are predicted by many new physics theories to describe the similarities between the lepton and quark sectors of the Standard Model and offer an attractive potential explanation for the lepton flavour anomalies observed at flavour factories. The ATLAS experiment has a broad program of direct searches for leptoquarks produced either in pairs or singly, coupling to the first-, second- or third-generation particles.

 Upgrade of ATLAS Hadronic Tile Calorimeter for the High Luminosity LHC / Moayedi, Seyedali (The University of Texas at Arlington) /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 High-Luminosity phase of LHC, delivering five times the LHC nominal instantaneous luminosity, is expected to begin in 2026. [...] ATL-TILECAL-SLIDE-2020-279.- Geneva : CERN, 2020 - 18 p.

 Performance of the ATLAS Tile Calorimeter / Harkusha, Siarhei (Institute of Physics, National Academy of Sciences) /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). [...] ATL-TILECAL-SLIDE-2020-278.- Geneva : CERN, 2020 - 14 p.
