Description

Top anti-top (tt) pair production at the Large Hadron Collider (LHC) is
often observed in the presence of additional high energy radiation. Similarly
the abundant tt production at the LHC allows us to probe high transverse momentum (p_{T} )
top quarks. This poster compares the latest measurements, using data recorded
by the ATLAS detector from 2015 to 2018, with different QCD predictions
showcasing how suited current theories are to estimating complex, multi-scale,
and above leading order tt̄ processes. Single and double-differential tt ̄ cross-
section measurements as functions of various event kinematic properties are presented.
Results are derived from proton-proton collisions, at a centre-of-mass energy
of 13 TeV, using events with a high p_{T} large-R jet, one muon or electron and at least two b-tagged jets in the final-state.
