Study VBS ZZ Production with the ATLAS experiment

The study of vector boson scattering (VBS) in ZZjj events produced in proton-proton collisions at 13 TeV will be reported. Data used in analysis were collected by the ATLAS experiment during Run II and correspond to a total integrated luminosity of 140 fb-1. Final states with four-charged lepton (4l) or two-charged lepton plus two neutrinos from the ZZ decays produced in association with two forward/backward jets are used to extract the VBS ZZjj signal. The inclusive VBS ZZjj production cross section will be measured. The electroweak VBS ZZ signal strength will be extracted with the BDT based analysis.
