Dark Matter from Binary Tetrahedral Flavor Symmetry

TL;DR

This paper extends a flavor symmetry model to include a dark matter candidate, a WIMP scalar, which preserves existing neutrino and quark mixing predictions and offers a viable dark matter particle around 780 GeV.

Contribution

It introduces a T' flavor symmetry extension that includes a Z2' odd scalar as a dark matter candidate, maintaining successful flavor predictions.

Findings

Dark matter candidate mass around 780 GeV

Model preserves neutrino mixing and Cabibbo angle predictions

Proposes a T' WIMP consistent with flavor symmetry constraints

Abstract

The minimal renormalizable T'xZ2 model (MRT'M) is slightly extended in its Higgs scalar sector such that the abelian part of the flavor symmetry enlarges to (Z2xZ2'). All standard model and original MRT'M states will transform trivially under Z2'. Inspired by the Valencia group's 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 (Phi_WIMP) with M_Phi \simeq 780 GeV.
