In the post-Higgs era, the theoretical challenge in flavor symmetry is to show how it should also predict a scalar boson very much like the observed 126 GeV particle at the LHC. I will discuss such a model of quark and lepton flavor symmetry based on $S_3$ proposed originally in 2004. I will show that this model has the unique prediction of a measurable branching fraction of up to $10^{-7}$ for $B_s o au^+ mu^-$, but that for $B_s o au^- mu^+$ is suppressed by an additional factor of $(m_mu/m_ au)^2$. |
