Abstract

The doubly charged Higgs boson is a theoretical particle that coulexist but has never been found. The Higgs Combine Tool (HCT) is a tool that uses Bayesian statistics to calculate limits based on particle accelerator data. I used 3000 inverse femtobarns of data which is the expected amount for the HL-LHC upgrade. I created text files that I fed into this tool that contained information about background, which are particles that look the same as the doubly charged Higgs boson, and how often I would expect the doubly charged Higgs boson to appear if it were to exist. Since these numbers vary depending on how much mass this Higgs has, I calculated different expected limits for different masses. This allowed me to calculate an expected lower limit on the mass of the doubly charged Higgs boson.
