## 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 $^{; ; +5.5}; ; _{; ; -5.2}; ;$ (stat) $^{; ; +2.7}; ; _{; ; -2.6}; ;$ (syst) pb, $\sigma_\mathrm{; ; WZ}; ; =$ 6.4 $^{; ; +2.5}; ; _{; ; -2.1}; ;$ (stat) $^{; ; +0.5}; ; _{; ; -0.3}; ;$ (syst) pb, and $\sigma_\mathrm{; ; ZZ}; ; =$ 5.3 $^{; ; +2.5}; ; _{; ; -2.1}; ;$ (stat) $^{; ; +0.5}; ; _{; ; -0.4}; ;$ (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.
