Unitarizing SIMP scenario with dark vector resonances

Abstract

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