标题： Mixing-induced CP Asymmetries in Inclusive $B$ Decays

摘要： 我们考虑由中性$B$介子衰变的非包容性通道中的粒子-反粒子混合引起的CP破坏不对称性。 不仅分支比显著，达到1%到50%的水平，而且由于显著的CKM相位，其中一些不对称性预计会很大。 非包容性总和部分稀释了不对称性，但假设局部夸克-强子对偶性，稀释因子是可以计算的，CKM参数可以可靠地提取。 我们详细讨论了从$B_d$介子衰变中的无 charm 最终态确定$sin 2\alpha$的方法，并调查了其他非包容性最终态的不对称性。 虽然可能还不能敏感地检测标准模型预测，但可以利用现有的非包容性中性$B$衰变数据样本进行有意义的CP破坏研究。 显示英文摘要

摘要： We consider CP violating asymmetries that are induced by particle-antiparticle mixing in inclusive channels of neutral $B$ meson decay. Not only are the branching ratios sizable, at the 1% to 50% level, but some of those asymmetries are expected to be large because of substantial CKM phases. The inclusive sum partially dilutes the asymmetries, but the dilution factor is calculable, assuming local quark-hadron duality, and CKM parameters can be reliably extracted. We discuss in detail the determination of $sin 2\alpha$ from charmless final states in decays of $B_d$ mesons and survey the asymmetries for other inclusive final states. While probably not yet sensitive to standard model predictions, meaningful CP violation studies can be conducted with existing data samples of inclusive neutral $B$ decays.
