Models for SIMP dark matter and dark photon

Abstract

We give a review on the SIMP paradigm and discuss a consistent model for SIMP dark mesons in the context of a dark QCD with flavor symmetry. The $Z^{\prime }$-portal interaction is introduced being compatible with stable dark mesons and is responsible for making the SIMP dark mesons remain in kinetic equilibrium with the SM during the freeze-out process. The SIMP parameter space of the $Z^{\prime }$ gauge boson can be probed by future collider and direct detection experiments.
