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 35.9 fb-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+33-31(stat)+29-23(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.
