Search for the charged-lepton-flavor-violating decay Z→eμ in pp collisions at √ s = 13 TeV with the ATLAS detector

A search for the charged-lepton-flavor-violating process Z→eμ is presented, using 139 fb−1 of √s=13 TeV pp collision data collected by the ATLAS experiment at the LHC. An excess in the eμ invariant mass spectrum near the Z boson mass would be a striking signature of new physics. No excess is obser...
