摘要:

标准模型对强子和轻子电偶极矩的预言与目前的实验结果相差甚远,因此,标准模型是对新物理效应的一种非常清晰的探索。特别是,在超对称框架与味道违反软条款大和潜在的可见效果的EDM通常是预期的。在这项工作中,我们系统地评估预测的EDMs在超越领先秩序(BLO)。事实上,我们表明,BLO贡献的EDM主导的领先阶(LO)的影响,在大区域的超对称参数空间。因此,将其纳入电子数据管理机制的评价是不可避免的。作为一个例子,我们显示的相关性的BLO效应的EDM的超对称$SU(5)$模型与右手中微子。

英文摘要:

The Standard Model predictions for the hadronic and leptonic electric dipole moments (EDMs) are well far from the present experimental resolutions, thus, the EDMs represent very clean probes of New Physics effects. Especially, within supersymmetric frameworks with flavor-violating soft terms large and potentially visible effects to the EDMs are typically expected. In this work, we systematically evaluate the predictions for the EDMs at the beyond-leading-order (BLO). In fact, we show that BLO contributions to the EDMs dominate over the leading-order (LO) effects in large regions of the supersymmetric parameter space. Hence, their inclusion in the evaluation of the EDMs is unavoidable. As an example, we show the relevance of BLO effects to the EDMs for a SUSY $SU(5)$ model with right-handed neutrinos.
