强相互作用大质量粒子(SiMP)最近被提出作为光热暗物质遗迹。在这里，我们考虑了SU(2)X隐藏规范理论的矢量SiMPs形式的SIMP机制的显式实现，其中偶然的守恒对称保护了暗物质的稳定性。在此设置中，我们提出了几种平衡暗扇区和可见扇区的方法。特别地，我们证明了亮暗希格斯门可以维持两个扇区之间的热平衡，就像具有广义Chern-Simons耦合的大质量暗矢量门可以维持两个扇区之间的热平衡一样，所有这些都与实验约束一致。
Strongly Interacting Massive Particles (SIMPs) have recently been proposed as light thermal dark matter relics. Here we consider an explicit realization of the SIMP mechanism in the form of vector SIMPs arising from an SU (2) X hidden gauge theory, where the accidental custodial symmetry protects the stability of the dark matter. We propose several ways of equilibrating the dark and visible sectors in this setup. In particular, we show that a light dark Higgs portal can maintain thermal equilibrium between the two sectors, as can a massive dark vector portal with its generalized Chern-Simons couplings to the vector SIMPs, all while remaining consistent with experimental constraints.
