Abstract
The doubly charged Higgs boson is a Higgs-like scalar particle that arises in certain extensions of the Standard Model. In a search for the H++ particle at the CMS experiment at the Large Hadron Collider (LHC) we investigate the decay of the H++ particle in the context of the left-right symmetric model (LRSM) so that we might reconstruct collected data to set mass limits on the Higgs. For Higgs reconstruction we test a minimum pT cut for electrons from 5 to 35 GeV and find that the 10 GeV cut yields the highest efficiency. We test this minimum pT cut against 12 different electron cuts and find none of these cuts to have a better performance. We also test a Z veto cut for same sign lepton pairs with invariant mass between 76 and 106 GeV which we find to boost performance.
