Abstract A simultaneous measurement of the three components of the top-quark and top-antiquark polarisation vectors in t-channel single-top-quark production is presented. This analysis is based on data from proton–proton collisions at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity …

Two-particle long-range azimuthal correlations are measured in photonuclear collisions using $1.7\phantom{\rule{4pt}{0ex}}{\mathrm{nb}}^{\ensuremath{-}1}$ of 5.02 TeV $\mathrm{Pb}+\mathrm{Pb}$ collision data collected by the ATLAS experiment at the CERN Large Hadron Collider. Candidate events are selected using a dedicated high-multiplicity photonuclear event trigger, a combination of …

A study of the charge conjugation and parity ($CP$) properties of the interaction between the Higgs boson and top quarks is presented. Higgs bosons are identified via the diphoton decay channel ($H\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$), and their production in association with a top quark pair …
