Measurements of the Electroweak Diboson Production Cross Sections in Proton-Proton Collisions at s\sqrt{s} =5.02 TeV Using Leptonic Decays

Abstract

The first measurements of diboson production cross sections in proton-proton interactions at a center-of-mass energy of 5.02 TeV are reported. They are based on data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 302 pb1^{-1}. Events with two, three, or four charged light leptons (electrons or muons) in the final state are analyzed. The WW, WZ, and ZZ total cross sections are measured as σWW=37.0+5.5^{+5.5}5.2_{-5.2}(stat)+2.7^{+2.7}2.6_{-2.6}(syst)  pb , σWZ=6.4+2.5^{+2.5}2.1_{-2.1}(stat)+0.5^{+0.5}0.3_{-0.3}(syst) pb, and σZZ=5.3+2.5^{+2.5}2.1_{-2.1}(stat)+0.5^{+0.5}0.4_{-0.4}(syst)  pb
