Measurement of the t¯tZ and t¯tW production cross sections in multilepton final states using 3.2 fb<sup>-1</sup> a of pp collisions at √s = 13 TeV with the ATLAS detector

A measurement of the t¯t Z and t¯t W 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 √s = 13 TeV recorded with the ATLAS detector at the Large Hadro...

description A measurement of the t¯t Z and t¯t W 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 √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<sup>-1</sup>. The inclusive cross sections are extracted using likelihood fits to signal and control regions, resulting in σ<sub>t¯tZ</sub>= 0.9 ± 0.3 pb and σ<sub>t¯tW</sub>= 1.5 ± 0.8 pb, in agreement with the Standard Model predictions.
