Abstract
A variety of exotic models predict a doubly charged Higgs-like particle that can be pair-produced in hadronic interactions via a Drell-Yan-like mechanism. The H++ and H-- can each decay to a pair of like-sign leptons (muons or electrons in this study) with TeV-scale mass, providing a distinctive event signature. Within Monte Carlo Drell-Yan events, there is a substantial amount of high mass like-sign lepton pairs, similar to the signal of the doubly charged Higgs. I determined the causes of Drell-Yan background and constructed a background estimate from the results. After identifying the causes of Drell-Yan background, I found underlying factors of each cause in order to use other measurements to predict their rate.
