扩展Higgs扇区的CP破坏及其对D^0 -> mu^+ mu^-衰变的影响

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

Daiji Kimura, Kang Young Lee, Takuya Morozumi

摘要:

我们研究了额外Higgs扇区的CP破坏对$D^0$衰变的影响。本文研究了两个Higgs二重态模型的CP偶和CP奇中性Higgs混合,指出混合的CP破坏效应是如何导致$D^0 \to μ^+ μ^-$的纵向μ子极化不对称性的.短距离贡献的不对称性对扩展Higgs扇区的CP破坏相很敏感。

英文摘要:

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 $D^0 \to μ^+ μ^-$. The asymmetry of the short-distance contribution is sensitive to the CP violating phase of the extended Higgs sector.
