Dark matter from binary tetrahedral flavor symmetry

Abstract

The minimal renormalizable T′×Z2 model (MRT′M) is slightly extended in its Higgs scalar sector such that the abelian part of the flavor symmetry enlarges to (Z2×Z2′). All standard model and original MRT′M states will transform trivially under Z2′. Inspired by the Valencia groupʼs A4 model building, we propose a T′ WIMP candidate as the lightest Z2′ odd scalar. This extension of the prior MRT′M model maintains the successful predictions for the neutrino mixing matrix and the Cabibbo angle, and provides an attractive candidate for dark matter (ΦWIMP) with MΦ≃780 GeV.
