论文摘要
我们通过在粒子频谱中引入一对矢量样(VL)双线来考虑在左右对称框架中的费米式暗物质(DM)。通过不间断的$ \ Mathcal {z} _2 $对称性来确保DM的稳定性。我们探索与观察到的遗物密度以及直接和间接检测横截面兼容的模型的参数空间。带电的深色fermions的存在为LHC和ILC的双电荷Higgs信号提供了有趣的可能性。在Multilepton最终状态下,分析了与DM观测一致的几种代表性参数选择,分析了将双带电标量衰减到黑暗扇区中的信号。
We consider a fermionic dark matter (DM) in the left-right symmetric framework by introducing a pair of vector-like (VL) doublets in the particle spectrum. The stability of the DM is ensured through an unbroken $\mathcal{Z}_2$ symmetry. We explore the parameter space of the model compatible with the observed relic density and direct and indirect detection cross sections. The presence of charged dark fermions opens up an interesting possibility for the doubly charged Higgs signal at LHC and ILC. The signal for the doubly charged scalar decaying into the dark sector is analyzed in multilepton final states for a few representative parameter choices consistent with DM observations.
