Abstract

A search for the charged-lepton-flavor-violating process Formula Presented is presented, using Formula Presented of Formula Presented Formula Presented collision data collected by the ATLAS experiment at the LHC. An excess in the Formula Presented invariant mass spectrum near the Formula Presented boson mass would be a striking signature of new physics. No excess is observed, and an upper limit Formula Presented is placed on the branching fraction at 95% confidence level, which is the most stringent limit to date.
