“…To cope with the large radiation doses and high pileup, the current ATLAS Inner Detector will be replaced with a new all-silicon Inner Tracker which will cover up to |eta| < 4. This poster presents recent results regarding the expected tracking performance of the Inner Tracker. …”

“…The high number of pile-up interactions was one of the major challenges faced during Run 2 and a continuous effort was needed to improve the pile-up rejection and to keep the trigger rate reasonable. This poster presents the techniques used to improve the Run 2 transverse missing momentum trigger performance, the full Run 2 performance and an outlook on further improvements for Run 3…”

“…The ATLAS collaboration collected the large datasets of $\it{pp}$ and Pb+Pb collisions in 2017 and 2018 corresponding to integrated luminosities of 0.26 fb$^{−1}$ and 1.38 nb$^{−1}$ respectively, at a centre-of-mass energy per nucleon pair of 5.02 TeV. In this poster, bottomonium states are reconstructed via the dimuon decay channel in the rapidity range of $|y|<1$, and their production in PbPb collisions is compared to that in pp collisions to extract the nuclear modification factor, $R_{\mathrm{AA}}$, as a function of event centrality and transverse momentum. …”

“…Measurements of the jet substructure in Pb+Pb collisions provide information about the mechanism of jet quenching in the hot and dense QCD medium created in these collisions, over a wide range of energy scales. This poster presents the ATLAS measurement of the suppression of yields of large-radius jets and its dependence on the jet substructure, characterized by the presence of sub-jets and their angular correlations. …”

“…The dimuon decay of the Higgs boson is the most promising process for probing the Yukawa couplings to the second generation fermions at the Large Hadron Collider (LHC). In this poster, we present a search for this important process using the data corresponding to an integrated luminosity of 139 fb$^{-1}$ collected with the ATLAS detector in pp collisions at $\sqrt{s}=13$ TeV at the LHC. …”
