Description

CP-Violation was first discovered in the weak interaction in the 1960s. Since its discovery, efforts have been made to find new sources of CP-Violation to account for matter anti-matter asymmetry. This project proposes a search for CP-Violation in the top Yukawa interaction through high energy muon collisions. Signal processes include $tth$, $tth\nu \nu$, and $tbh\mu \nu$ decaying semi-leptonically. We present cross-section dependence of signal processes with varying CP-phase, $\alpha$, at different center of momentum energies. We show luminosity required for $5\sigma$ discovery and give results to achieve $2\sigma$ exclusion given the Standard Model case, $\alpha$ = 0, at 1 TeV, 10TeV, and 30TeV at a muon collider.
