Non-Abelian Discrete Dark Matter

Understand

We consider the minimal model in which dark matter is stabilized by a non-Abelian discrete symmetry.

• The symmetry group is taken to be D_3, which is the smallest non-Abelian finite group.
• The minimal model contains (nontrivial) singlet and doublet scalar representations of D_3 which couple to the Standard Model fields via the Higgs portal.
• This construction predicts two species of dark matter over much of the parameter space.
