关于Mu-Tau味对称性的破缺

On the breaking of mu-tau flavor symmetry

Zhen-hua Zhao

摘要:

根据相对大的$θ^{}_{13}$的观察,必须考虑适当地破坏$μ$对称性,否则这将导致$θ^{}_{13}$(以及$θ^{}_{23} = π/4$)消失。因此,我们调查各种破坏性的模式,并相应地确定那些是现象学上可行的。此外,由某些特定物理学(例如,重整化群方程运行效应)。

英文摘要:

In light of the observation of a relatively large $θ^{}_{13}$, one has to consider breaking the $μ$-$τ$ symmetry properly which would otherwise result in a vanishing $θ^{}_{13}$ (as well as $θ^{}_{23} = π/4$). Therefore, we investigate various symmetry-breaking patterns and accordingly identify those that are phenomenologically viable. Furthermore, the symmetry-breaking effects arising from some specific physics (e.g., the renormalization group equation running effect) are discussed as well.
