Abstract

Measurements of fiducial and total inclusive cross sections for W and Z boson production are presented in proton-proton collisions at root s = 5.02 and 13TeV. Electron and muon decay modes (l = e or mu) are studied in the data collected with the CMS detector in 2017, in dedicated runs with reduced instantaneous luminosity. The data sets correspond to integrated luminosities of 298 +/- 6 pb(-1) at 5.02TeV and 206 +/- 5 pb(-1) at 13TeV. Measured values of the products of the total inclusive cross sections and the branching fractions at 5.02TeV are sigma(pp -> W+ X)B(W -> l nu) = 7300 +/- 10 (stat) +/- 60 (syst) +/- 140 (lumi) pb, and sigma(pp -> Z+ X)B(Z -> l(+) l(-)) = 669 +/- 2 (stat)+/- 6 (syst)+/- 13 (lumi) pb for the dilepton invariant mass in the range of 60-120 GeV. The corresponding results at 13TeV are 20480 +/- 10 (stat)+/- 170 (syst)+/- 470 (lumi) pb and 1952 +/- 4 (stat)+/- 18 (syst)+/- 45 (lumi) pb. The measured values agree with cross section calculations at next-to-next-to-leading-order in perturbative quantum chromodynamics. Fiducial and total inclusive cross sections, ratios of cross sections of W+ and W- production as well as inclusive W and Z boson production, and ratios of these measurements at 5.02 and 13TeV are reported.
