论文摘要
在最小的超对称标准模型（MSSM）在由单线超级场扩展的最小超对称标准模型（MSSM）中，当单线扇区和MSSM扇区之间的耦合很小时，单元扇区可以是带有超对称性的准黑暗扇形（SUSY）。我们在这种情况下研究了宇宙学现象，并获得以下观察结果：（i）在参数空间中，通过自我相互作用的单利诺暗物质（SIDM）求解小型宇宙学量表异常，一阶相变（FOPT）可以很容易地发生，但需要在MEV下方进行相当相当轻的暗物质； （ii）FOPT和SIDM指示的相应参数空间可以通过检测近未实现的项目（例如Lisa，Tianqin和Taiji）处的相变引力波（GWS）来部分覆盖。因此，最近开发的GW天文学可能是对这种SUSY场景的新颖调查。
In the minimal supersymmetric standard model (MSSM) extended by a singlet superfield, when the coupling between the singlet sector and the MSSM sector is tiny, the singlet sector can be a quasi dark sector with supersymmetry (SUSY). We investigate the cosmological phenomena in this scenario and obtain the following observations: (i) In the parameter space solving the small cosmological scale anomalies via self-interacting singlino dark matter (SIDM), a first-order phase transition (FOPT) can readily happen but requires rather light dark matter below MeV; (ii) The corresponding parameter space indicated by FOPT and SIDM can be partially covered by detecting the phase-transition gravitational waves (GWs) at the near-future projects, such as LISA, TianQin and Taiji. Therefore, the recently developed GW astronomy could be a novel probe to such a SUSY scenario.
