"Hard probes of heavy ion collisions with ATLAS" / Mc Ginn, Christopher (University of Colorado Boulder (US)) /ATLAS Collaboration
This talk gives an overview of the latest hard process measurements in heavy ion collision systems with the ATLAS detector at the LHC, utilizing the high statistics 5.02 TeV Pb+Pb data collected in 2018. These include multiple measurements of jet production and structure, which probe the dynamics of the hot, dense Quark-Gluon Plasma formed in relativistic nucleus-nucleus collisions; measurements of electroweak boson production to constrain the modifications of nuclear parton densities and test the Glauber model and binary scaling picture of heavy ion collisions; and measurements of quarkonia and heavy flavor production to probe the QGP medium properties.

Rare flavor physics decays at ATLAS and CMS / Grummer, Aidan (Fermi National Accelerator Lab. (US)) /ATLAS Collaboration
The ATLAS and CMS experiments have performed measurements of B-meson rare decays proceeding via suppressed electroweak flavour changing neutral currents. This talk will focus on the latest results from the ATLAS and CMS on B^0_s → mu mu, B^0 → mu mu, B^0 → K^*0 mu mu and B^+ → K^(*)+ mu mu decays. [...]

Performance of LGAD sensors for the ATLAS High-Granularity Timing Detector / Cui, Han (Chinese Academy of Sciences (CN)) /ATLAS Collaboration
We report on the layout and performance of Low-Gain Avalanche Detectors (LGAD) produced for the ATLAS High Granularity Timing Detector (HGTD) foreseen for the HL-LHC upgrade of the ATLAS experiment. The HGTD is a multi-layer silicon-based detector with a total active area of 6.4 $m^2$ covering the pseudo-rapidity region between 2.4 and 4.0 with timing sensors with a primary resolution of at least 50 ps/hit, and capable of providing 30-50 ps/track time resolution.

Jet flavour tagging for the ATLAS Experiment / Shlomi, Jonathan (Weizmann Institute of Science (IL)) /ATLAS Collaboration
Jet flavour tagging for the ATLAS Experiment The ability to identify jets stemming from the hadronisation of b-quarks (b-jets) is crucial for the physics program of ATLAS. The higher pileup conditions and the growing interest for measurements including c-jets and for searches in the high transverse momentum regime make the task more and more complex. [...]

Higgs boson measurements in couplings to quarks and leptons with the ATLAS experiment / Horii, Yasuyuki (Nagoya University (JP)) /ATLAS Collaboration
Testing the Yukawa couplings of the Higgs boson to quarks and leptons is important to understand the origin of fermion masses. The talk presents several new measurements in Higgs boson decays to two bottom quarks or two tau leptons, searches for Higgs boson decays to two charm quarks or two muons, as well as indirect constraints of the charm-Yukawa coupling.

Measurements of the differential production cross sections of a top-quark-antiquark pair in association with a Z boson at $\sqrt{s}$ = 13 TeV with the ATLAS detector / ATLAS Collaboration /ATLAS Collaboration
An increasing center-of-mass energy of proton-proton collisions and higher luminosities at the CERN Large Hadron Collider make it possible to study rare processes of the Standard Model (SM). In this talk, the measurements of the differential cross sections of top-quark-antiquark production in association with a Z boson ($t\bar{t}Z$) are presented. [...]

Search for the Single Production of Vector-Like Top Quarks in the Decay $T \rightarrow Ht$ or $T \rightarrow Zt$ with the ATLAS Detector / Buxo Vazquez, Carlos Josue (Michigan State University (US)) /ATLAS Collaboration
A search for the single production of a vector-like top quark ($T$) decaying as $T \rightarrow Ht$ or $T \rightarrow Zt$ using the full Run-2 dataset of the ATLAS detector at $\sqrt s=13$ TeV is presented. The talk will motivate the searches for these particles and will focus on the recent public result of the analysis targeting the $T \rightarrow Ht/Zt$ decay topology in the 1-lepton channel. [...]
