超对称SU中高尺度下的Sflavor混合映射（5）
Sflavor mixing map viewed from a high scale in supersymmetric SU(5)
摘要：
我们采用质量插入的方法，以模型无关的方式研究了超对称SU（5）大统一情形中的味破坏。我们研究如何夸克和轻子部门的可观测量限制sfermion混合。在软标量质量较低的情况下，轻子味破坏过程对右手下型平方子的味结构提供了严格的约束。特别是，mu -> e γ被证明是非常容易受到1-3和2-3混合，由于从顶部汤川耦合的标量质量项10的辐射校正。相反，在最佳值附近具有较高标量质量的情况下，夸克扇区输入（如B介子混合和强子电偶极矩）基本上决定了sfermion混合的空间。我们还讨论了最近在B_s混合相中观察到的偏差，即将进行的实验的预计灵敏度，以及即使在引入解决方案以修复不正确的夸克-轻子质量关系之后，如何保持轻子限制的功率。
英文摘要：
We study flavor violation in a supersymmetric SU(5) grand unification scenario in a model-independent way employing mass insertions. We examine how the quark and the lepton sector observables restrict sfermion mixings. With a low soft scalar mass, a lepton flavor violating process provides a stringent constraint on the flavor structure of right-handed down-type squarks. In particular, mu -> e gamma turns out to be highly susceptible to the 1-3 and 2-3 mixings thereof, due to the radiative correction from the top Yukawa coupling to the scalar mass terms of 10. With a higher scalar mass around the optimal value, in contrast, the quark sector inputs such as B-meson mixings and hadron electric dipole moment, essentially determine the room for sfermion mixing. We also discuss the recent deviation observed in B_s mixing phase, projected sensitivity of forthcoming experiments, and ways to maintain the power of leptonic restrictions even after incorporating a solution to fix the incorrect quark-lepton mass relations.
