Measurements of the electroweak diboson production cross sections in proton-proton collisions at $\sqrt{s}=$ 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 pb${}^{-1}$. 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 ${\sigma }_{\mathrm{WW}}=$ 37.0 ${}_{-5.2}^{+5.5}$ (stat) ${}_{-2.6}^{+2.7}$ (syst) pb, ${\sigma }_{\mathrm{WZ}}=$ 6.4 ${}_{-2.1}^{+2.5}$ (stat) ${}_{-0.3}^{+0.5}$ (syst) pb, and ${\sigma }_{\mathrm{ZZ}}=$ 5.3 ${}_{-2.1}^{+2.5}$ (stat) ${}_{-0.4}^{+0.5}$ (syst) pb. All measurements are in good agreement with theoretical calculations at combined next-to-next-to-leading order quantum chromodynamics and next-to-leading order electroweak accuracy.
