论文摘要
我们探索了Slim模型的变体的参数空间，该变体用单线和双重的标量和两代右手中微子扩展了SM，其中最轻的MEV中有质量到GEV区域，并扮演了暗物质候选者的作用。我们强加了当前的对撞机和天体物理限制，以及违反Lepton风味的实验的边界。我们还将利用电子后坐力的XENON实验中的发现潜力视为可能的直接检测信号。尽管该模型中的DM是嗜血杆菌的，但由于重电的介体，预测的横截面太低。
We explore the parameter space of a variant of the SLIM model, which extends the SM with a singlet and a doublet of complex scalars and two generations of right-handed neutrinos, the lightest of which has a mass in the MeV to GeV region and plays the role of Dark Matter candidate. We impose the current collider and astrophysical constrains, as well as bounds from Lepton Flavour Violating experiments. We also consider the discovery potential in the XENON experiment exploiting the electron recoil as a possible direct detection signal. Despite the DM in this model being leptophilic, the predicted cross sections are too low due to the heavy charged mediator.
