dc.description.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=13TeVrecorded 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→Wb + −q) =123+33−31(stat)+29−23(syst)fb, where stands for electrons, muons, or τleptons, with observed and expected significances of 3.7 and 3.1 standard deviations, respectively.	en
