Abstract
A search for a long-lived, massive particle decaying to a μμ, ee, or eμ pair is presented using the ATLAS detector with 32.8 fb−1
of pp collisions at √s = 13 TeV at the LHC. The analysis searches for at least two leptons originating from a displaced vertex while
remaining agnostic to all other activity in the event. The expected sensitivity of a SUSY model and a generic Z’ model will be presented.
