强U(1)规范理论中的SIMP

SIMP from a strong U(1) gauge theory with a monopole condensation

摘要:

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。我们首先解释了一个非阿贝尔版本的模型与一个额外的单重场,这是混合与希格斯场,以保持隐藏和标准模型(SM)部门之间的动力学平衡。混合导致的信号,将被检测到未来的对撞机实验,直接DM检测实验,和束流转储实验。然后我们研究了一个带标量的U(1)理论,其中U(1)带电粒子被束缚在标量凝聚中。在这个模型中,由于Higgs场的径向分量可以与Higgs场混合,所以我们不需要引入额外的单重场。

英文摘要:

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.
