摘要

给出了b \to s \bar q q跃迁对电荷量贡献的综合质量插入公式。该方法阐明了超对称对FCNCs的贡献计算背后的物理原理。该结果应用于B \to K \pi衰变CP不对称性的差异分析。结果表明，超对称不是造成这种差异的原因。

Mass Insertion Formula for Chargino Contribution to ΔB = 1 Wilson Coefficients and Its Application to CP Asymmetries of B → Kπ

The comprehensive mass insertion formula of the b \to s \bar q q transitions was provided for the chargino contributions. The method clarifies physics behind the calculations of the supersymmetric contributions to FCNCs. The result was applied to the analysis of the difference of the CP asymmetries of the B \to K\pi decays. It is shown that the supersymmetry is not responsible for the discrepancy.
