Flavor unification, dark matter, proton decay, and other observable predictions with lowscale S{sub 4} symmetry
Abstract
We show how gauge coupling unification is successfully implemented through nonsupersymmetric grand unified theory, SO(10)xG{sub f}(G{sub f}=S{sub 4},SO(3){sub f},SU(3){sub f}), using a lowscale flavorsymmetric model of the type SU(2){sub L}xU(1){sub Y}xSU(3){sub C}xS{sub 4} recently proposed by Hagedorn, Lindner, and Mohapatra, while assigning matterparity discrete symmetry for the dark matter stability. For gauge coupling unification in the singlestepbreaking case, we show that a coloroctet fermion and a hyperchargeless weak triplet fermionic dark matter are the missing particles needed to complete its minimal supersymmetric standard modelequivalent degrees of freedom. When these are included, the model automatically predicts the nonsupersymmetric grand unification with a scale identical to the minimal supersymmetric standard model/grand unified theory scale. We also find a twostepbreaking model with PatiSalam intermediate symmetry where the dark matter and a lowmass coloroctet scalar or the fermion are signaled by grand unification. The protonlifetime predictions are found to be accessible to ongoing or planned searches in a number of models. We discuss the grand unified origin of the light fermionic triplet dark matter, the coloroctet fermion, and their phenomenology.
