Measurement of the WZ production cross section in pp                        collisions at $\\sqrt(s) =$ 13 TeV

The WZ production cross section in proton–proton collisions at s=13 TeV is measured with the CMS experiment at the LHC using a data sample corresponding to an integrated luminosity of 2.3 fb−1. The measurement is performed in the leptonic decay modes WZ→ℓνℓ′ℓ′, where ℓ,ℓ′=e,μ. The measured cross section for the range 60
