味标记和非标记$D^0 \rightarrow K^-π^+$衰变中CP破坏的研究

Study of CP Violation in Flavor Tagged and Untagged $D^0 \rightarrow K^-π^+$ Decays

E. Won, B. R. Ko, B. Golob

摘要:

我们回顾了味道标记和未标记的$D^0 \rightarrow K^{-}π^{+}$衰变中的$CP$破坏观测值,并评估了两种衰变之间的$CP$不对称性差异。我们注意到,这个通常被忽略的差异原则上不是零,并且在未来的$B$工厂实验中可能是显著的。我们还构建了一个表达式来提取强相位差之间的$\bar{D}^0 \rightarrow K^-π^+$和$D^0 \rightarrow K^-π^+$衰变,独立于现有的实验方法。

英文摘要:

We review $CP$-violating observables in flavor tagged and untagged $D^0 \rightarrow K^{-}π^{+}$ decays and evaluate the $CP$ asymmetry difference between the two decays. We note that this commonly neglected difference is not zero in principle and can be significant in future $B$ factory experiments. We also construct an expression to extract the strong phase difference between $\bar{D}^0 \rightarrow K^-π^+$ and $D^0 \rightarrow K^-π^+$ decays, independently of existing experimental methods.
