Abstract
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 √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.
