Abstract

The same sign invariant mass histograms, produced from running simulated proton-proton collisions that produce doubly charged Higgs bosons samples, are unexpectedly skewed. While it was expected that the graphs would have a clean spike at 800 GeV, they had long tails on the right and left sides. The goal of the analysis was to use different methods to include final state radiation photons in order to recover the invariant mass, which would lessen the tails on the produced graphs. Many methods were tried, each using different physical principles such as delta r, phi, eta, and pt. Each attempted method produced a new same sign invariant mass histogram. After superimposing the new graphs over the old ones, and comparing them all, it was concluded that none of the methods had a significant impact on the invariant mass and the graphs.
