Measurement of the total and differential cross-sections of tt‾W production in pp collisions at √s = 13 TeV with the ATLAS detector
Original language description
Measurements of inclusive and differential production cross-sections of a top-quark-top-antiquark pair in association with a W boson (tt‾W) are presented. They are performed by targeting final states with two same-sign or three isolated leptons (electrons or muons) and are based on √s = 13 TeV proton-proton collision data with an integrated luminosity of 140 fb−1, recorded from 2015 to 2018 with the ATLAS detector at the Large Hadron Collider. The inclusive tt‾WttW production cross-section is measured to be 880 ± 80 fb, compared to a reference theoretical prediction of 745 ± 50 (scale) ± 13 (2-loop approx.) ± 19 (PDF, αss) fb. Differential cross-section measurements characterise this process in detail for the first time.
