Abstract
A measurement is presented of the associated production of a single top quark and a Z boson. The study uses data from proton–proton collisions at √s = 13 TeV recorded by the CMS experiment, corresponding to an integrated luminosity of 35.9fb⁻¹. Using final states with three leptons (electrons or muons), the tZq production cross section is measured to be σ(pp→tZq→Wbl⁺l⁻q) =123[superscript +33][subscript −31](stat)[superscript +29][subscript −23](syst)fb, where l stands for electrons, muons, or τ leptons, with observed and expected significances of 3.7 and 3.1 standard deviations, respectively. Keywords: SM; Single top; Cross section; tZq
