摘要

标准模型的一个重要测试是由无魅力带电两体$b$ -强子衰变到具有介子和介子的最终状态。事实上,使用这些衰变测量的$C\!P$不对称性对标准模型之外的新物理很敏感,因为衰变振幅从与树级跃迁相似的环级图中得到贡献。我们报告了利用运行1 (3fb $^{-1}$)收集的数据在LHCb实验中获得的无粲\textit{b}强子双体衰变的最新结果。

CP violation in $B^{0}_{(s)}\rightarrow h^{+}h^{-}$
An important test of the Standard Model is represented by the charmless charged two-body $b$-hadron decays to final states with kaons and pions. In fact the $C\!P$ asymmetries measured using these decays are sensitive to new physics beyond the Standard Model since the decay amplitudes receive contributions from loop-level diagrams with magnitudes similar to those from tree-level transitions. We report the most recent results on the charmless \textit{b}-hadron two-body decays obtained by the LHCb experiment using the data collected in Run~1 (3 fb$^{-1}$).
