Cross section measurement for the production of ZZ → llvv with the ATLAS detector

This talk presents a measurement of ZZ production with the ATLAS detector at the Large Hadron Collider. The measurement is carried out focusing on the final state with one Z boson decaying to two charged leptons and the other Z boson decaying to two neutrinos, using data collected during the Run-2 period in pp collisions at √s = 13 TeV, corresponding to an integrated luminosity of 139 fb⁻¹. The inclusive and differential cross-sections for the production of the ZZ → llvv channel are measured. A multivariable analysis is performed to optimize the background rejection for the measurement.
