Measurement of the Z / ??? ?? cross section in pp collisions at ?s=13TeV and validation of ? lepton analysis techniques

Abstract: A measurement is presented of the Z / ??? ?? cross section in pp collisions at s=13TeV, using data recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 2.3fb-1. The product of the inclusive cross section and branching fraction is measured to be ?(pp?Z/??+X)B(Z/?????)=1848±12(stat)±67(syst \,+\,lumi) pb, in agreement with the standard model expectation, computed at next-to-next-to-leading order accuracy in perturbative quantum chromodynamics. The measurement is used to validate new analysis techniques relevant for future measurements of ? lepton production. The measurement also provides the reconstruction efficiency and energy scale for ? decays to hadrons+?? final states, determined with respective relative uncertainties of 2.2 and 0.9%.
