标准模型的CP破坏和幺正三角检验

CP-violation and unitarity triangle test of the Standard Model

S. M. Bilenky

摘要:

本文讨论了标准模型中夸克扇区CP破坏的唯象问题。我们考虑夸克混合的SM,标准和Wolfenstein参数化的$CKM$混合矩阵和幺正三角形。讨论了$K^{0}_{L}$和$B_{d}^{0} (\bar B_{d}^{0})$衰变中CP破坏的唯象.讨论了现有数据的标准么正三角形拟合。在附录A中我们比较了$K^{0}\leftrightarrows \bar K^{0}$、$B_{d,s}^{0}\leftrightarrows \bar B^{0}_{d,s}$等振荡和中微子振荡。在附录B中,我们在Weisskopf-Wigner近似下导出了$M^{0}- \bar M^{0}$系统的演化方程。

英文摘要:

Phenomenological issues of the CP violation in the quark sector of the Standard Model are discussed. We consider quark mixing in the SM, standard and Wolfenstein parametrization of the $CKM$ mixing matrix and unitarity triangle. We discuss the phenomenology of the CP violation in $K^{0}_{L}$ and $B_{d}^{0} (\bar B_{d}^{0})$-decays. The standard unitarity triangle fit of the existing data is discussed. In appendix A we compare the $K^{0}\leftrightarrows \bar K^{0}$, $B_{d,s}^{0}\leftrightarrows \bar B^{0}_{d,s}$ etc oscillations with neutrino oscillations. In Appendix B we derive the evolution equation for $M^{0}- \bar M^{0}$ system in the Weisskopf-Wigner approximation.
