Evidence for tWZ production in proton-proton collisions at √s=13 TeV in multilepton final states
Original language description
The first evidence for the standard model production of a top quark in association with a W boson and a Z boson is reported. The measurement is performed in multilepton final states, where the Z boson is reconstructed via its decays to electron or muon pairs. At least one W boson, associated or from top quark decay, decays leptonically, too. The analysed data were recorded by the CMS experiment at the CERN LHC in 2016-2018 in proton-proton collisions at root s = 13 TeV, and correspond to an integrated luminosity of 138 fb(-1). The measured cross section is 354 +/- 54(stat) +/- 95(syst) fb, and corresponds to a statistical significance of 3.4 standard deviations.
