Measurement of the WZ production cross section in pp collisions at sqrt(s) = 13 TeV

The WZ production cross section in proton–proton collisions at View the MathML sources=13 TeV is measured with the CMS experiment at the LHC using a data sample corresponding to an integrated luminosity of 2.3 fb−1. The measurement is performed in the leptonic decay modes WZ→lνl′l′WZ→lνl′l′, where l,l′=e,μl,l′=e,μ. The measured cross section for the range 60<ml′l′<120 GeV60<ml′l′<120 GeV is View the MathML sourceσ(pp→WZ)=39.9±3.2(stat) (syst)−3.1+2.9±0.4(theo)±1.3(lumi) pb, consistent with the standard model prediction.
