Vector-like quarks, leptoquarks and new gauge bosons searches in ATLAS / Haley, Joseph (Oklahoma State University (US)) /ATLAS Collaboration
The Standard Model of Particle Physics explains many natural phenomena yet remains incomplete. Leptoquarks (LQs) are hypothetical particles predicted to mediate interactions between quarks and leptons, bridging the gap between the two fundamental classes of particles. [...]

Observation of quantum entanglement in top-quark pair production using $pp$ collisions of $\sqrt{s} = 13$~\TeV\ with the ATLAS detector
We report the highest-energy observation of entanglement so far in top--antitop quark events produced at the Large Hadron Collider, using a proton$-$proton collision data set with a centre-of-mass energy of $\sqrt{s}=13$ TeV and an integrated luminosity of 140 fb$^{-1}$. [...]

Top quark angular correlations at the LHC with ATLAS and CMS / Howarth, James William (University of Glasgow (GB)) /ATLAS Collaboration
Latest results on multi-differential production cross sections as a function of angular variables using collision data collected by ATLAS and CMS. In particular, those variables derived from the full spin density production matrix for ttbar production, the polarisation of top quarks in single-top weak production as well as variables related to measurements of the charge and forward-backward asymmetry..

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.

Treatment of top-quark backgrounds in extreme phase spaces: the ''top $p_{T}$ reweighting'' and novel data-driven estimations in ATLAS and CMS / Serkin, Leonid (Abdus Salam Int. Cent. Theor. Phys. (IT))
The top quark plays an important role in searches for physics beyond the SM, both as a dominant background and as a key signature for the signal. [...]

Treatment of top-quark backgrounds in extreme phase spaces: top pT mismodelling. / Serkin, Leonid (INFN Gruppo Collegato di Udine and ICTP, Trieste) /ATLAS Collaboration
The top quark plays an important role in searches for physics beyond the SM, both as a dominant background and as a key signature for the signal. This presentation covers recent LHC searches for SUSY and Exotica with signatures with top quarks, with a focus on the treatment of the top quark background at high pT. [...]
