我们指出,在D^*K^-$类型的衰变中,中性介子是$D^{*0}$和$D^{*0}$的混合物,在$D^*$被重构为$D^*$和$D\伽马$的情况下,存在一个有效的强位相差$\pi$。我们考虑了使用这些模式测量$\PhI_3$的后果,其中一些模式是深刻和有益的。
We point out that in decays of the type $B^- \to D^* K^-$, where the neutral $D^*$ meson is an admixture of $D^{*0}$ and $\bar{D}^{*0}$, there is an effective strong phase difference of $\pi$ between the cases that the $D^*$ is reconstructed as $D\pi^0$ and $D\gamma$. We consider the consequences for measurements of $\phi_3$ using these modes, some of which are profound and beneficial.
