Abstract
Many extensions of the Standard Model predict the doubly charged Higgs boson (H++), a beyond the Standard Model particle. To search for the H++, we compare data with Monte Carlo background estimates through a validation plot to examine if there is a statistically significant difference. To generate this plot, we first created a framework to process and work with data files from CMS servers. Then, to compare the data and Monte Carlo, we created an analysis framework that produces separate validation plots – graphing opposite sign invariant mass – for each decay channel and mass target. The plots are published to a webpage for simple visualization. Separating plots by decay channel and mass target allows us to analyze the data’s relationship with the individual background channels – TTBar, multiboson, ZZ, and Drell-Yan. The validation plots are used to confirm that we understand our signal and background properly.
