Description
We study a CP-violating top Yukawa coupling at muon collider through $\mu^-\mu^+\to t\bar{t}h\nu\bar{\nu}$ process. The gauge invariant Lagrangian is obtained by a dimension-6 operator. Although the cross section and distributions are gauge invariant, amplitudes calculated in the Feynman Diagram (FD) gauge allow us to understand the origin of the energy and angular dependence of CP violating asymmetries, and may help us preparing the future search strategy.
