Prediction for $\Gamma (H\to {\tau }^{+}{\tau }^{-})/\Gamma (H\to {\mu }^{+}{\mu }^{-})$ from Non-Abelian Flavor Symmetry

Abstract

It is shown that the ratio of branching ratios in Higgs boson decay $r=\Gamma (H\to {\tau }^{+}{\tau }^{-})/\Gamma (H\to {\mu }^{+}{\mu }^{-})$ in a simplified ($T^{{}^{\prime }}\times Z_2$) model is $(r{)}_{T^{{}^{\prime }}\times Z_2}\simeq 0.001$. This prediction is on a footing with the successful one in $(s,d)$ mixing, $\tan 2{\Theta }_{12}=1/3(\sqrt{2})$. 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 ($T^{{}^{\prime }}\times Z_2$) flavor symmetry.
