Description

Most of the interesting physics signatures at the LHC require the identification of prompt non-fake leptons or photons. Non-fake leptons are usually isolated and have no activity around them hence it is important to define an “isolation energy” around leptons to reduce any contamination from non-prompt and fake objects. In this proceeding, reoptimization studies have been performed to decrease the pileup dependence of the lepton isolation variables for the High Higgs ($m_{4l} \geq$ 200 GeV) Mass and Low Higgs (115 $\leq m_{4l} \leq$ 130 GeV) Mass.
