Abstract (data abstract)
CERN-LHC. The WZ production cross section in proton-proton collisions at sqrt(s) = 13 TeV is measured with the CMS experiment at the LHC using a data sample corresponding to an integrated luminosity of 2.3 inverse fb. The measurement is performed in the leptonic decay modes WZ to l nu l' l', where l, l' = e, mu. The measured cross section for the range 60 < m[l'l'] < 120 GeV is 39.9 +/- 3.2 (stat) +2.9/-3.1 (syst) +/- 0.4 (theo) +/- 1.3 (lumi) pb, consistent with the standard model prediction. Fiducial region definition - leading Z lepton pt > 20 GeV - subleading Z lepton pt > 10 GeV - W lepton pt > 20 GeV - lepton |eta| < 2.5 - Z invariant mass between 60 and 120 GeV - any same-flavor opposite-sign lepton pair invariant mass > 4 GeV Total cross section region definition - Z invariant mass between 60 and 120 GeV - any same-flavor opposite-sign lepton pair invariant mass > 4 GeV
