Measurement of the associated production of a single top quark and a Z boson in pp collisions at s=13TeV
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...

| Summary: | 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 → Wb�+�−q) = 123+33
−31(stat)
+29
−23(syst) fb,
where � stands for electrons, muons, or τ leptons, with observed and expected significances of 3.7 and
3.1 standard deviations, respectively |
