 Search for Higgs boson decays to beyond-the-Standard-Model light bosons in four-lepton events with the ATLAS detector at $\sqrt{s}=13$ TeV / Chiu, Yu Him Justin (University of Victoria) /ATLAS Collaboration Current measurements permit the branching ratio of the SM Higgs to BSM particles to be as high as approximately 30%. Such exotic decays of the Higgs are well-motivated theoretically. [...] ATL-PHYS-SLIDE-2019-546.- Geneva : CERN, 2019 - 15 p.

 Observation of electroweak $W^{\pm}Z$ boson pair production in association with two jets in pp collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector and prospects for New Physics / Sampsonidou, Despoina (Aristotle University of Thessaloniki) /ATLAS Collaboration The observation of electroweak W±Z production in association with two jets in the fully leptonic channel in proton–proton collisions is presented. The data collected by the ATLAS detector at the Large Hadron Collider in 2015 and 2016 at a centre-of-mass energy of sqrt(s) = 13 TeV are used, corresponding to an integrated luminosity of 36.1 fb−1.

 Observation of H->bb decays in the VH production mode and first differential measurement with the ATLAS detector / Ambroz, Luca (University of Oxford, Particle Physics) /ATLAS Collaboration H ->bb decays allow to probe the Yukawa coupling of the Higgs boson to down type quarks. Observing these processes at the LHC is extremely challenging due to the large multi-jet background; however, this can be greatly suppressed by triggering on Missing Transverse Energy and charged leptons coming from the decay of a weak vector boson produced together with the Higgs.

 Direct top-quark decay width measurement at $\sqrt{s}=13$ TeV with the ATLAS experiment / Dado, Tomas (Comenius University) /ATLAS Collaboration Excellent performance of the LHC accelerator allows precise measurements of top quark properties. A direct measurement of the top-quark decay width is presented using full Run 2 dataset collected by the ATLAS detector at $\sqrt{s}=13$ TeV, corresponding to an integrated luminosity of $139~\text{fb}^{-1}$.

 Measurements of the Higgs production cross section in the $H \rightarrow \tau \tau$ decay channel with the ATLAS experiment / Murrone, Alessia (INFN Milano and Universita' di Milano, Dipartimento di Fisica) /ATLAS Collaboration The Higgs to tau tau decay is a considerably important decay channel because it allows to directly measure the Yukawa coupling to fermions and to measure the Higgs boson properties. During the Run 2 of the LHC the energy has increased to $\sqrt{s}=13$ TeV and the luminosity has increased as well. [...] ATL-PHYS-SLIDE-2019-539.- Geneva : CERN, 2019 - 1 p.

 The ATLAS Hardware Track Trigger design towards first prototypes / Moreira De Carvalho, Ana Luisa (Laboratorio de Instrumenta\c{c}\~ao e Fisica Experimental de Particulas - LIP, Lisboa) /ATLAS Collaboration In the High Luminosity LHC, planned to start with Run4 in 2026, the ATLAS experiment will be equipped with the Hardware Track Trigger (HTT) system, a dedicated hardware system able to reconstruct tracks in the silicon detectors with short latency. This HTT will be composed of about 700 ATCA boards, based on new technologies available on the market, like high speed links and powerful FPGAs, as well as custom-designed Associative Memories ASIC (AM), which are an evolution of those used extensively in previous experiments and in the ATLAS Fast Tracker (FTK).

 Search for high-mass dilepton resonances in the full Run-2 ATLAS dataset / Dreyer, Etienne (Simon Fraser University) /ATLAS Collaboration Having enabled discoveries of Standard Model resonances in previous decades, the dilepton invariant mass spectrum remains a vital experimental probe of today’s high energy frontier. Multiple benchmark scenarios beyond the Standard Model anticipate new high-mass neutral mediators whose clean signatures in the dilepton final state have been a prime target for searches at the Large Hadron Collider.
