## Abstract

The purpose of this project is to automatically generate background and signal estimates for the H++. Drell-Yan is one possible path of Higgs production, but 4 lepton production at 800 GeV is quite rare, meaning the data becomes sparse near 800 due to the low probability of events generating in that range. To calculate background in this case and gain consistency, we create a fit using the more consistent lower mass ranges, and then use this fit to derive event numbers from these large mass ranges. A power law fit is used as it produces a good fit. Using this fit and values for the higher lepton bins, we can calculate a background estimate for our various production pathways. The range of the fit is the range from 150-1700 GeV, I will be presenting the final event yield in the talk.
