| 英文摘要 | A measurement of the t (t) over barz and t (t) over barw production cross sections in final states with either two same-charge muons, or three or four leptons (electrons or muons) is presented. the analysis uses a data sample of proton-proton collisions at root s = 13 tev recorded with the atlas detector at the large hadron collider in 2015, corresponding to a total integrated luminosity of 3.2 fb(-1). the inclusive cross sections are extracted using likelihood fits to signal and control regions, resulting in sigma(t (t) over barz) = 0.9 +/- 0.3 pb and sigma(t (t) over barw) = 1.5 +/- 0.8 pb, in agreement with the standard model predictions. |
