Measurement of the total and differential cross-sections of ▫$tt^{-}W$▫ production in ▫$\it {pp}$▫ collisions at ▫$\sqrt s$▫ = 13 TeV with the ATLAS detectorAad, Georges ...Measurements of inclusive and differential production cross-sections of a top-quark-top-antiquark pair in association with a W boson ( ) are presented. They are performed by targeting final states ... with two same-sign or three isolated leptons (electrons or muons) and are based on = 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 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, αs) fb. Differential cross-section measurements characterise this process in detail for the first time. Several particle-level observables are compared with a variety of theoretical predictions, which generally agree well with the normalised differential cross-section results. Additionally, the relative charge asymmetry of and is measured inclusively to be = 0.33 ± 0.05, in very good agreement with the theoretical prediction of 0.322 ± 0.003 (scale) ± 0.007 (PDF), as well as differentially.Vir: The journal of high energy physics [Elektronski vir]. - ISSN 1029-8479 (Vol. 2024, [article no.] 131, May 2024, str. 1-75)Vrsta gradiva - e-članek ; neleposlovje za odrasleLeto - 2024Jezik - angleškiCOBISS.SI-ID - 198641155
