SUSY S4味模型中的Slepton质量矩阵、μ-> e γ衰变和EDM

Slepton Mass Matrices, mu -> e gamma Decay and EDM in SUSY S4 Flavor Model

Hajime Ishimori, Morimitsu Tanimoto

摘要:

本文用SUSY SU(5)大统一理论讨论了$S_4$味模型中的Slepton质量矩阵。通过在超引力理论框架下考虑引力中介作用,我们估计了引起$μ\rightarrow e + γ$衰变的Slepton质量矩阵中的超对称性破缺项。当$m_{\text{SUSY}}$和$m_{1/2}$低于500 GeV时,我们得到了$μ\rightarrow eγ$作为$10^{-13}$的比值的一个下界.轻子质量矩阵的非对角项对轻子的EDM也有贡献。预测的电子EDM约为$10^{-29}-10^{-28}$ cm。我们的预测有望在不久的将来的实验中得到验证。

英文摘要:

We discuss slepton mass matrices in the $S_4$ flavor model with SUSY SU(5) GUT. By considering the gravity mediation within the framework of supergravity theory, we estimate the SUSY breaking terms in the slepton mass matrices, which contribute to the $μ\rightarrow e + γ$ decay. We obtain a lower bound for the ratio of $μ\rightarrow eγ$ as $10^{-13}$ if $m_{\text{SUSY}}$ and $m_{1/2}$ are below 500GeV. The off diagonal terms of slepton mass matrices also contribute to EDM of leptons. The predicted electron EDM is around $10^{-29}-10^{-28}$cm. Our predictions are expected to be tested in the near future experiment.
