Abstract
The left-right symmetric model says that the doubly charged Higgs boson should exist, and we are searching for it. To prove its existence, we need to be able to differentiate it from other four lepton-producing processes. Drell-Yan may be one of the most important backgrounds for the search but has very low efficiency along with a large cross section. As there are too few events to make a good estimate with, Monte Carlo events were first evaluated manually to understand the interaction types that occurred for Drell-Yan to produce four leptons instead of two. Using this information, we then wrote a program to automate the process. From the results of this analysis, a reliable background estimate for Drell-Yan can be made to assist in the search for the doubly charged Higgs boson.
