论文摘要
在这次演讲中，我回顾了多年来在$ b $衰减中进行的CP竞争观测值所进行的各种测量。这些包括间接的CP不对称，直接CP不对称和三产物。在寻找新物理学（NP）的背景下，所有这些都进行了讨论。 NP的唯一提示出现在（i）$ b \toπk$衰减中，（ii）3型$ b \ tokππ$和$ b \ to k {\ bar k} k $衰变，其中提取（loop-level）$ qup的值可能与使用（Tree-Level）$ B^+^^^^^^^^^^^^^^^^（*） k^{（*）+} $衰变。 CP侵入可观察物也可用于区分提议的模型，以解释$ b \ to $ b \ tosμ^+μ^ - $和$ b \ toCτ{\barν}_τ$衰减的当前异常。
In this talk, I review the various measurements that have been made over the years of CP-violating observables in $B$ decays. These include indirect CP asymmetries, direct CP asymmetries, and triple products. All are discussed in the context of the search for new physics (NP). The only hints of NP have appeared in (i) $B \to πK$ decays and (ii) 3-body $B \to Kππ$ and $B \to K {\bar K}K$ decays, where the extracted (loop-level) value of $γ$ may differ from the value found using (tree-level) $B^+ \to D^{(*)} K^{(*)+}$ decays. CP-violating observables may also be used to distinguish among the models proposed to explain the current anomalies observed in $b \to sμ^+ μ^-$ and $b \to c τ{\barν}_τ$ decays.
