关于标准模型中K与Bd系统CP破坏的一致性

On the consistency between CP violation in the K vs. Bd systems within the Standard Model

Diego Guadagnoli

摘要:

在K和Bd系统中,间接CP破坏分别由参数λ_K和sin 2 β量化。在标准模型中,CP破坏相位的唯一性意味着,在π_K和sin 2 β之间的测量允许预测另一个。由于这两个参数都得到了很好的测量,这就变成了一个强有力的一致性测试。我讨论了这个测试的状态,特别是在最近的进展,在K-K公式。

英文摘要:

In the K and Bd systems, indirect CP violation is quantified by the parameters epsilon_K and sin 2beta respectively. Within the Standard Model, the uniqueness of the CP violating phase implies that the measurement of either between epsilon_K and sin 2beta permits to predict the other. Since both these parameters are very well measured, this turns into a powerful test of consistency. I discuss the status of this test, especially in the light of recent advances on the epsilon_K formula.
