description The rejection of forward jets originating from additional proton--proton interactions (pile-up) is crucial for a variety of physics analyses at the LHC, including Standard Model measurements and searches for physics beyond the Standard Model. This note presents a method for tagging forward jets originating from pile-up interactions using the ATLAS particle flow algorithm. The overall pile-up rejection power observed in Z + jets POWHEG + PYTHIA8 simulated events for jets with transverse momentum between 20 and 60 GeV, is 34% and 51% with an efficiency of 87% and 76% respectively for selecting hard-scatter jets.
