我们提供了一个强相互作用大质量粒子（SIMP）的变体模型，其中复合暗物质来自强相互作用U(1)理论。我们首先用一个附加的单重态场解释了该模型的非阿贝尔版本，该单重态场与希格斯场混合，以维持隐藏和标准模型（SM）扇区之间的动力学平衡。混合产生的信号将被未来的对撞机实验、直接DM检测实验和波束转储实验检测到。然后我们研究了带有标量单极子的U(1)理论，其中U(1)带电粒子受到单极子凝聚的限制。在该模型中，单极子的径向分量可以与希格斯场混合，因此我们不需要引入额外的单线场。
We provide a variant model of strongly interacting massive particle (SIMP), where composite dark matter comes from a strongly interacting U(1) theory. We first explain a non-Abelian version of the model with an additional singlet field, which is mixed with the Higgs field to maintain the kinetic equilibrium between the hidden and Standard Model (SM) sectors. The mixing leads to signals that would be detected by future collider experiments, direct DM detection experiments, and beam-dump experiments. Then we investigate a U(1) theory with a scalar monopole, where U(1) charged particles are confined by monopole condensation. In this model, the radial component of monopole can mix with the Higgs field, so that we do not need to introduce the additional singlet field.
