Search for pair-production of vector-like quarks in lepton+jets final states containing at least one b-tagged jet using the Run 2 data from the ATLAS experiment / ATLAS Collaboration
state using 140 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}= 13$ TeV collected with the ATLAS detector. The search is optimised for vector-like top-quarks ($T$) that decay into a $W$ boson and a $b$-quark, with one $W$ boson decaying leptonically and the other hadronically. [...]

Top quark properties overview (asymmetries, CP violation, spin correlations, FCNC) at the LHC / Kempster, Jacob Julian (University of Birmingham (GB)) /ATLAS Collaboration
The remarkably large integrated luminosity collected by the ATLAS and CMS detectors during Run2 in proton–proton collisions at a centre-of-mass of 13 TeV allows to use the large sample of top quark events to explore a variety of properties of top quark production and decay and to probe the presence on new physics that might break well established symmetries or manifest itself in rare processes. Measurements of are presented for all three components of the top-quark and antiquark polarisation vectors in t-channel single-top-quark production, normalised differential cross sections as a function of the charged lepton angles.

First Measurements of Spin Correlation Using Semi-leptonic $t\bar{t}$ Events at ATLAS / Lemmer, Boris
This poster presents the results of the first measurement of $t\bar{t}$ spin correlations in the lepton+jets channel at ATLAS. By using a dedicated up/down type quark separation in the reconstruction, two hadronic spin analyzers were used to measure spin correlations..
