CP violation of Extended Higgs sector and Its impact on D^0 -> mu^+ mu^-
decay    [PDF]

Daiji Kimura, Kang Young Lee, Takuya Morozumi

We study the impact of the CP violation of the extra Higgs sector on $D^0$ decay. The CP even and CP odd neutral Higgs mixing of the two Higgs doublet model is studied and we show how the CP violating effect of the mixing may lead to the longitudinal muon polarization asymmetry of $D^0 \to \mu^+ \mu^-$. The asymmetry of the short-distance contribution is sensitive to the CP violating phase of the extended Higgs sector.
