The standard HVM

Abstract

We discuss a standard hierarchical VEVs model which predicts the leptonic mixing angles in terms of the Cabibbo angle, and masses of strange and charm quarks as $\sin {\theta }_{12}^{\ell }\ge 1-2\sin {\theta }_{12}$, $\sin {\theta }_{23}^{\ell }\ge 1-\sin {\theta }_{12}$, and $\sin {\theta }_{13}^{\ell }\ge \sin {\theta }_{12}-\frac{m_s}{m_c}$ for the normal mass ordering of neutrinos. This results in very precise predictions of the leptonic mixing angles given by $\sin {\theta }_{12}^{\ell }=0.55\pm 0.00134$, $\sin {\theta }_{23}^{\ell }=0.775\pm 0.00067$, and $\sin {\theta }_{13}^{\ell }=0.1413-0.1509$. Furthermore, we predict neutrinos to be the Dirac kind disfavouring the inverted mass hierarchy. The standard hierarchical VEVs model predicts a possible new class of the dark matter candidate, named as neutrinic dark matter.
