探测$B^0_s \rightarrow K^{0}_{\rm S} π^{+}π^{-}$衰变中的CP破坏

Probing CP violation in $B^0_s \rightarrow K^{0}_{\rm S} π^{+}π^{-}$ decays

Tim Gershon, Thomas Latham, Rafael Silva Coutinho

摘要:

三体无粲强子衰变$B^0_s \rightarrow K^{0}_{\rm S} π^{+}π^{-}$为寻找CP破坏效应和检验粒子物理的标准模型提供了许多新的可能性。这些包括拟合到衰减时间整合的最终状态的Dalitz图分布,衰减时间依赖(但没有初始状态风味标记)拟合到Dalitz图分布,以及完全衰减时间依赖和风味标记拟合。这些不同的方法的相对灵敏度进行了研究。

英文摘要:

The three-body charmless hadronic decay $B^0_s \rightarrow K^{0}_{\rm S} π^{+}π^{-}$ provides a number of novel possibilities to search for CP violation effects and test the Standard Model of particle physics. These include fits to the Dalitz-plot distributions of the decay-time-integrated final state, decay-time-dependent (but without initial state flavour tagging) fits to the Dalitz-plot distribution, as well as full decay-time-dependent and flavour tagged fits. The relative sensitivities of these different approaches are investigated.
