论文摘要
我们考虑了稀有$ b_d $和$ b_s $衰减的时间相关分析，由$ b \ tosν\barν$ transions介导。包含时间演化使我们能够在这些过程中对CP-ODD阶段具有特定敏感性的特定敏感性构建新颖的可观察物。还探讨了在存在风味的情况下对CP违反相应时间集成测量的敏感性。我们为SM中的这些可观察物提供了精确的预测，并探索了它们目前对新CP竞选NP贡献的敏感性，并计划了未来的$ b $ - 物理实验。因此，这些可观察到的物品在$ b \ tosν\barν$过渡中提供了独特的CP违规探针。
We consider the time-dependent analysis of rare $B_d$ and $B_s$ decays mediated by $b\to s ν\bar ν$ transitions. The inclusion of time evolution allows us to construct novel observables with specific sensitivity to CP-odd phases in these processes. The sensitivity to CP violation of corresponding time-integrated measurements in presence of flavor-tagging is also explored. We provide precise predictions for these observables in the SM and explore their sensitivity to new CP-violating NP contributions at present and planned future $B$-physics experiments. As such, these observables provide unique probes of CP violation in $b \to s ν\bar ν$ transitions.
