## Abstract

The Higgs Combine Tool (HCT) is a tool to calculate limits and do statistical analysis on the data collected by particle detectors. We create and edit data cards and then calculate the limit on the cross-section of the production of a particle, given a background estimate, using a Bayesian technique. We then used the HCT to create graphs to show the results more clearly. The specific type of analysis we used was a Markov Chain Monte Carlo calculation. We applied this to create preliminary sensitivities for the search for a doubly charged Higgs boson.
