© 2021, CERN for the benefit of the CMS collaboration.The production of Z boson pairs in proton–proton (p p) collisions, p p → (Z / γ∗) (Z / γ∗) → 2 ℓ2 ℓ′, where ℓ, ℓ′= e or μ , is studied at a center-of-mass energy of 13TeV with the CMS detector at the CERN LHC. The data sample corresponds to an integrated luminosity of 137fb-1, collected during 2016–2018. The Z Z production cross section, σtot(pp→ZZ)=17.4±0.3(stat)±0.5(syst)±0.4(theo)±0.3(lumi) pb, measured for events with two pairs of opposite-sign, same-flavor leptons produced in the mass region 60
