| Abstract: | Measurements of both the inclusive and differential production cross sections of a top-quark-antiquark pair in association with a Z boson (t ̄tZ) are presented. The measurements are performed by targeting final states with three or four isolated leptons (electrons or muons) and are based on √s = 13 TeV proton-proton collision data with an integrated luminosity of 139 fb-1, recorded from 2015 to 2018 with the ATLAS detector at the CERN Large Hadron Collider. The inclusive cross section is measured to be σt ̄tZ = 0.99±0.05 (stat.) ± 0.08 (syst.) pb, in agreement with the most precise theoretical predictions. The differential measurements are presented as a function of a number of kinematic variables which probe the kinematics of the t ̄tZ system. Both absolute and normalised differential cross-section measurements are performed at particle and parton levels for specific fiducial volumes and are compared with theoretical predictions at different levels of precision, based on χ2 ndf and p value computation. Overall, good agreement is observed between the unfolded data and the predictions. |
