CP Violation in Top Physics at the NLC

Abstract

Top quark is extremely sensitive to non-standard CP violating phases. General strategies for exposing different types of phases at the NLC are outlined. SUSY phase(s) cause PRA in $t\to Wb$. The transverse polarization of the $τ$ in the reaction $t\to bτν$ is extremely sensitive to a phase from the charged Higgs sector. Phase(s) from the neutral Higgs sector cause appreciable dipole moment effects and lead to sizable asymmetries in $e^+e^-\to t\bar tH^0$ and $e^+e^-\to t\bar tν_e\barν_e$.}]
