Book Synopsis Measurement of the TtZ Production Cross Section in the Final State with Three Charged Leptons Using 36.1 Fb^-1 of Pp Collisions at 13 TeV at the ATLAS Detector by : Nils-Arne Rosien
Book excerpt: A measurement of the production cross section for a top quark pair in association with a Z boson (ttZ) is presented in this PhD thesis. Final states with exactly three charged leptons (electrons or muons) are used, taking into account the decay of the top quark pair in the lepton+jets channel and the decay of the Z boson into two charged leptons. The dataset used for this analysis corresponds to 36.1 fb^-1 of proton-proton collisions at a centre-of-mass energy of 13 TeV, recorded during 2015 and 2016 by the ATLAS detector at the Large Hadron Collider. The result of a profile likelihood fit ...
