Description
The ability to correct jets and jet shapes for the contributions of multiple uncorrelated proton-proton
interactions (pileup) largely determines the ability to identify new physics via highly boosted hadronic
decays of W, Z, and Higgs bosons, or top quarks. We present a new method that operates at the level of the
jet constituents and provides both a performance improvement and a simplification compared to existing
methods. Comparisons of the new method with existing methods along with predictions of the impact of pileup
during the LHC run II will be presented. We will also discuss methods that may improve the determination of
the missing pt in high pileup environment and a connection between pileup subtraction and the underlying
event subtraction in heavy ion collisions.
