 Operational Experience and Performance with the ATLAS Pixel detector at the Large Hadron Collider / Kocian, Martin (SLAC National Accelerator Laboratory) /ATLAS Collaboration The tracking performance of the ATLAS detector relies critically on its 4-layer Pixel Detector which has undergone significant hardware and readout upgrades to meet the challenges imposed by the higher collision energy, pileup and luminosity delivered by the Large Hadron Collider (LHC), with record breaking instantaneous luminosities of 2 x 10^34 cm-2 s-1 recently surpassed. The key status and performance metrics of the ATLAS Pixel Detector are summarized, and the operational experience and requirements to ensure optimum data quality and data taking efficiency will be described, with special emphasis on radiation damage experience..

 The operational experience, challenges and performance of the ATLAS Semiconductor Tracker during LHC Run-2 / Hirose, Shigeki (Albert-Ludwigs-Universitaet Freiburg) /ATLAS Collaboration The Large Hadron Collider (LHC) recently completed its Run-2 operation period (2015-2018) which delivered an integrated luminosity of 156 fb-1 at the centre-of-mass pp collision energy of 13~TeV. This marked 10 years of successful operation by the ATLAS Semiconductor Tracker (SCT), which operated during Run-2 with instantaneous luminosity and pileup conditions that were far in excess of what the SCT was originally designed to meet.

 The ATLAS ITk Strip Detector System for the Phase-II LHC Upgrade / Wonsak, Sven (University of Liverpool) ; ATLAS Collaboration /ATLAS Collaboration The ATLAS experiment at the Large Hadron Collider is currently preparing for a major upgrade of the Inner Tracking for the Phase-II LHC operation (known as HL-LHC), scheduled to start in 2026. In order to achieve the integrated luminosity of 4000 fb-1, the instantaneous luminosity is expected to reach unprecedented values, resulting in about 200 proton-proton interactions in a typical bunch crossing.

 Test Beam Characterization of Prototype Modules for the ATLAS Inner Tracker Strip Detector / Rossi, Edoardo (DESY, Hamburg and Zeuthen) /ATLAS Collaboration After more than ten years of operations, starting from 2024 the LHC will be upgraded to the High-Luminosity LHC (HL-LHC). The HL-LHC will deliver a total integrated luminosity of up to 4000fb-1 in about ten years, with a peak luminosity five times higher than that which was reached before the current LHC shutdown.

 Angular analyses of t-channel single top production and decay / Bi, Runyu (University of Pittsburgh) ; Boudreau, Joseph (University of Pittsburgh) /ATLAS Collaboration Angular analyses of t-channel single top production and decay Electroweak production of single top in the t-channel at the LHC yields large samples of polarized top quarks which can be used to accurately constrain the Wtb vertex. This vertex can be parameterized in terms of complex anomalous couplings $V_L$, $V_R$, $g_L$, and $g_R$, which enter into an effective Lagrangian.

 Extending the search for di-higgs decaying to bbbb in the boosted channel with the ATLAS detector / Paredes Saenz, Santiago Rafael (University of Oxford, Particle Physics) /ATLAS Collaboration After the discovery of the Higgs boson, new searches can now change their focus towards using it as a tool to probe both the Standard Model and new physics. One of such probes is the search for pair production of Higgs bosons [...] ATL-PHYS-SLIDE-2019-759.- Geneva : CERN, 2019 - 30 p.

 Measurement of the top quark mass using a leptonic invariant mass in pp collisions at $\sqrt{s}$ = 13TeV with the ATLAS detector / Wilkins, Lewis Joseph (Department of Physics, Royal Holloway and Bedford New College) /ATLAS Collaboration A measurement for the top-quark mass $m_t$ in the $\ell$+jets channel for $t\bar{t}$ events is presented, with an experimental technique used for the first time in ATLAS. Semi-leptonic decays of $b$-hadrons produced by the same top which produced the leptonically decaying $W$-boson are exploited. [...] ATL-PHYS-SLIDE-2019-758.- Geneva : CERN, 2019 - 1 p.

The proton–proton collision data collected by the ATLAS experiment from 2015 to 2018 at a centre-of-mass energy of 13 TeV are used, corresponding to an integrated luminosity of 139 fb$^{-1}$.
