Abstract
Within the ATLAS experiment the Prompt Lepton Isolation Tagger (PLIT) has been developed to serve as an essential tool to distinguish between prompt muons originating from the decays of the Higgs, W or Z bosons and non-prompt muons generated in the semi-leptonic decays of
𝑏- and 𝑐-hadrons. Its central role is to effectively mitigate the presence of fake and non-prompt leptons in various multi-lepton final state analyses. This contribution presents the ongoing efforts
in developing and optimizing this tagger for Run-3 data analyses.
