Measurement of ZZ production in the ℓℓνν final state with the ATLAS detector in pp collisions at √s = 13 TeV

Abstract

This paper presents a measurement of ZZ production with the ATLAS detector at the Large Hadron Collider. The measurement is carried out in the nal state with two charged leptons and two neutrinos, using data collected during 2015 and 2016 in pp collisions at ps = 13TeV, corresponding to an integrated luminosity of 36.1 fb􀀀1. The integrated cross-sections in the total and ducial phase spaces are measured with an uncertainty of 7% and compared with Standard Model predictions, and di erential measurements in the ducial phase space are reported. No signi cant deviations from the Standard Model predictions are observed, and stringent constraints are placed on anomalous couplings corresponding to neutral triple gauge-boson interactions.
