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<mℓ+ℓ-[removed]engopenAccesshttps://creativecommons.org/licenses/by/4.0/Measurements of pp → ZZ production cross sections and constraints on anomalous triple gauge couplings at √s = 13 TeVarticle81300062543100000410.1140/epjc/s10052-020-08817-82-s2.0-85104267607
