Abstract

The decay of the doubly charged Higgs is as follows: two quarks annihilate into a Z boson, which pair produces an H++ and H--, which both then decay into 4 final state leptons. We attempt to find more precise cuts to eliminate the most significant backgrounds – Drell-Yan, ZZ, ttbar, and QCD. We also calculate the significance. By predicting better pT (transverse momentum) cuts on the backgrounds for the different 4 leading lepton states, we maximize the significance, which makes the signal identification easier.
