非阿贝尔离散味对称自发破缺模型的预测性

Predictivity of models with spontaneously broken non-Abelian discrete flavor symmetries

Mu-Chun Chen, Maximilian Fallbacher, Yuji Omura, Michael Ratz, Christian Staudt

摘要:

在一类超对称味模型中,预测是基于理论的某些子部分的剩余对称性,例如带电轻子和中微子的剩余对称性。然而,所谓的flavon场的真空期望值通常会修改设置的Kähler势,从而改变预测。我们推导出简单的解析公式,使我们能够理解这些修正对质量和混合参数的预测的影响。此外,我们还讨论了真空取向和风味改变中性电流的影响。我们的结果也可以应用到非超对称味模型。

英文摘要:

In a class of supersymmetric flavor models predictions are based on residual symmetries of some subsectors of the theory such as those of the charged leptons and neutrinos. However, the vacuum expectation values of the so-called flavon fields generally modify the Kähler potential of the setting, thus changing the predictions. We derive simple analytic formulae that allow us to understand the impact of these corrections on the predictions for the masses and mixing parameters. Furthermore, we discuss the effects on the vacuum alignment and on flavor changing neutral currents. Our results can also be applied to non--supersymmetric flavor models.
