Measurement of the tt?Z and tt?W production cross sections in multilepton final states using 3.2 fb -1 of pp collisions at s = 13 TeV with the ATLAS detector
M Aaboud, G Aad, B Abbott, J Abdallah et autres
A measurement of the tt¯Ztt¯Z and tt¯Wtt¯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√=13s=13 TeV recorded with …
