Four-lepton production in proton-proton collisions, pp → (Z/γ ∗)(Z/γ ∗) → 4, where = e or μ, is studied at a center-of-mass energy of 13 TeV with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 35.9 fb−1. The ZZ production cross section, σ (pp → ZZ) = 17.2 ± 0.5 (stat) ± 0.7 (syst) ± 0.4 (t
