Dark pion is the one of the most natural and realistic model to make 3 → 2 contact interactions
among models of the Strongly Interacting Massive Particle (SIMP). In this model, there is a per-
turbativity problem to satisfy the relic density with the self-annihilation. So we show the pertur-
bativity problem can be alleviated and the SIMP pion model become more realistic by including
dark vector mesons.
