摘要:

提出的“米兰达程序”的分析Dalitz图CP不对称性在带电的B和D衰变在一个模型无关的方式进行了扩展和改进。在寻找新动力学(ND)时,需要通过顺序$λ^6$的CKM CP现象学的复杂性。三体末态的详细分析还有其他巨大的优点:(1)它们为我们提供了更有力的工具来判断所观察到的CP不对称性是否代表ND的表现及其特征。(ii)许多优点已经可以通过“米兰达程序”获得,而无需构造详细的达利兹情节描述。(iii)一个研究CP不对称独立的生产不对称。我们说明了第二代米兰达程序的力量与$B_d/\bar B_d$衰减到最终状态$K_Sπ+π-$的时间积分率的例子作为试用运行与评论$B^{\pm} \to K^{\pm}π^+π^-/K^{\pm}K^+K^-$。

英文摘要:

The `Miranda Procedure' proposed for analyzing Dalitz plots for CP asymmetries in charged B and D decays in a model-independent manner is extended and refined. The complexity of CKM CP phenomenology through order $λ^6$ is needed in searches for New Dynamics (ND). Detailed analyses of three-body final states other great advantages: (i) They give us more powerful tools for deciding whether an observed CP asymmetry rep- resents the manifestation of ND and its features. (ii) Many advantages can already be obtained by the `Miranda Procedure' without construction of a detailed Dalitz plot de- scription. (iii) One studies CP asymmetries independent of production asymmetries. We illustrate the power of a second generation Miranda Procedure with examples with time integrated rates for $B_d/\bar B_d$ decays to final states $K_Sπ+π-$ as trial runs with comments on $B^{\pm} \to K^{\pm}π^+π^-/K^{\pm}K^+K^-$.
