摘要

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) congruent to S(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. Nontrivial interactions under D(3) lead to a novel thermal history of dark matter, while the multi-component nature of dark matter can be tested by future direct detection experiments.
