Inclusive and differential cross-section measurements of t t ¯ Z $$ t\overline{t}Z $$ production in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector, including EFT and spin-correlation interpretations

open access: yesJournal of High Energy Physics
Measurements of both the inclusive and differential production cross sections of a top-quark-top-antiquark pair in association with a Z boson ( t t ¯ Z $$ t\overline{t}Z $$ ) are presented. Final states with two, three or four isolated leptons (electrons

Constraints on effective field theories via quadruple-differential angular decay rates from t-channel single-top-quark production at s = 13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
Events with t-channel single top quarks are used to probe effective field theory operators in s = 13 $$ \sqrt{s}=13 $$ TeV proton–proton collision data corresponding to 140 fb −1 recorded by the ATLAS detector at the Large Hadron Collider.

Top Quark Physics

open access: yes, 1999
In this contribution I review the physics of top quarks at a future Linear Collider. Main emphasis is put on the process e+ e- to ttbar close to threshold. Different physical observables, their sensitivity to the basic parameters and their theoretical prediction are discussed.

Observation of t t ¯ $$ t\overline{t} $$ production in the lepton+jets and dilepton channels in p+Pb collisions at s NN $$ \sqrt{s_{\textrm{NN}}} $$ = 8.16 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
This paper reports the observation of top-quark pair production in proton-lead collisions in the ATLAS experiment at the Large Hadron Collider. The measurement is performed using 165 nb −1 of p+Pb data collected at s NN $$ \sqrt{s_{\textrm{NN}}} $$ = 8 ...
