左右对称与电偶极矩。进行全球分析

Left-right symmetry and electric dipole moments. A global analysis

Michael J. Ramsey-Musolf, Juan Carlos Vasquez

摘要:

我们执行一个全球性的配合使用的电偶极矩(EDM)的反磁系统的上下文中的最小左右对称模型的搜索结果。通过这种方式,我们解开了新的“左-右”电弱和$\barθ$的贡献,不能使用一个单一的EDM系统分离。虽然拟合是针对特定模型完成的,但该方法可以应用于任何粒子物理模型。最后,我们重新审视$D$系数在$β$衰减的约束,并发现目前的EDM边界不排除观察这种T-违反影响在一个可能的下一代$β$衰减实验。

英文摘要:

We perform a global fit using results of searches for electric dipole moments (EDM) of diamagnetic systems within the context of the minimal left-right symmetric model. In this way, we disentangle the new "left-right" electroweak and $\barθ$ contributions that cannot be separated using a single EDM system. Although the fit is done for a specific model, the approach can be applied to any particle physics model. Finally, we revisit the constraint on the $D$ coefficient in $β$-decay and find that current EDM bounds do not preclude observation of this T-violating effect in a possible next generation $β$-decay experiment.
