Measurement of total and differential t-channel production cross-sections of single top quarks and top antiquarks in proton-proton collisions at 13 TeV using the full Run 2 dataset recorded with the ATLAS detector — Benedikt Gocke2, Dominic Hirschbühl1, Lukas Kretschmann1, Adrian Miemczyk1, Olaf Nackenhorst2, Joshua Reidelstürz1, •Maren Stratmann1, and Wolfgang Wagner1 — 1Bergische Universität Wuppertal, Wuppertal, Deutschland — 2Technische Universität Dortmund, Dortmund, Deutschland
The t-channel production is the dominant process for single top quark and single top antiquark production at the LHC. The presented analysis measures the total cross-sections for top-quark and top-antiquark production σ(tq) and σ(tq) as well as the combined cross-section σ(tq+tq) and the cross-section ratio Rt=σ(tq)/σ(tq). The differential production cross-sections are measured as a function of the transverse momentum pT and rapidity |Y| of the top-quark and top-antiquark respectively. The full Run 2 dataset recorded with the ATLAS detector in the years 2015-2018 is used.
