Analyzing the t tbar Background of the Doubly Charged Higgs Boson

The Standard Model is the current basis of particle physics, providing a basic set of particles and interactions. Since its introduction, researchers have been attempting to discover new particles to prove an extended set of theories. One of these particles is the doubly charged Higgs boson. If found, the Doubly Charged Higgs would have many implications for other areas of particle physics such as the existence of a right-handed neutrino. One important background process for the doubly charged Higgs search involves t and tbar, has a signal of 2 leptons and two neutrinos, but it shows as 4 leptons, the same signal as the doubly charged Higgs. This creates the potential for a cut to reduce background. We also must understand where the two leptons come from in this background. We will analyze the t and tbar background to find why four leptons are being detected, which will lead to background cuts to aid in our search for the Doubly Charged Higgs.
