从非阿贝尔味对称性预测$Γ(H\to τ^+τ^-)/ Γ(H\to μ^+μ^-)$

Prediction for $Γ(H\to τ^+τ^-)/ Γ(H\to μ^+μ^-)$ from Non-Abelian Flavor Symmetry

Paul H. Frampton, Shinya Matsuzaki

摘要:

结果表明,在简化的($T^{'} \times Z_2$)模型中,希格斯玻色子衰变$r = Γ(H \to τ^+τ^-)/Γ(H\to μ^+μ^-)$的分支比之比为$(r)_{T^{'} \times Z_2} \simeq 0.001$ .这一预测与$(s, d)$混合中的成功预测$\tan 2 Θ_{12} = {1/3}(\sqrt{2})$是一致的。$r$的该值与最小标准模型的值相差非常大的因子(超过250,000),并且可以为($T^{'} \times Z_2$)风味对称性提供确凿证据。

英文摘要:

It is shown that the ratio of branching ratios in Higgs boson decay $r = Γ(H \to τ^+τ^-)/Γ(H\to μ^+μ^-)$ in a simplified ($T^{'} \times Z_2$) model is $(r)_{T^{'} \times Z_2} \simeq 0.001$. This prediction is on a footing with the successful one in $(s, d)$ mixing, $\tan 2 Θ_{12} = {1/3}(\sqrt{2})$. This value for $r$ differs from that of the minimal standard model by a very large factor (over 250,000) and can provide a smoking gun for ($T^{'} \times Z_2$) flavor symmetry.
