| 英文摘要 | 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, root 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 sigma (pp -> tzq -> wbl(+)l(-)q) = 123(-31)(+33)(stat)(-23)(+29)(syst) fb, where l stands for electrons, muons, or tau leptons, with observed and expected significances of 3.7 and 3.1 standard deviations, respectively. c) 2018 the author. published by elsevier b.v. |
