Abstract

We present new selection cuts for doubly charged Higgs bosons decaying into tau particles. The variables of the data include the leading lepton transverse momentum, same-sign invariant mass, opposite-sign invariant mass, and missing transverse energy values of each interaction. We also collect these values from data on each of the significant background events for the doubly charged Higgs decaying into tau particle interaction (QCD, DY, ttbar, and ZZ). For each variable, we superimpose background and signal data into a single histogram. We then run a script to compute the selection cut with the maximum significance, which we approximated using the number of signal events divided by the square root number of background events. After finding the optimal selection cuts for each variable, we apply all cuts and present the results below.
