Weakly supervised anomaly detection for resonant new physics in the dijet final state using proton-proton collisions at (Formula presented.) with the ATLAS detector

An anomaly detection search for narrow-width resonances beyond the Standard Model that decay into a pair of jets is presented. The search is based on 139 fb(-1) of proton-proton collisions at root s = 13 TeV recorded during 2015-2018 with the ATLAS detect
