- 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 <math display="inline"><mrow><mn>302</mn><mtext> </mtext><mtext> </mtext><msup><mrow><mi>pb</mi></mrow><mrow><mo>-</mo><mn>1</mn></mrow></msup></mrow></math>. Events with two, three, or four charged light leptons (electrons or muons) in the final state are analyzed.

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.
