论文摘要
Super-Weak模型是标准模型的U（1）扩展。除了介导器$ z'$之外，还添加了一个单线标量符号$χ$来处理SM真空的元稳定性，并引入了右撇子中微子来说明非呈现的中性中微子群众。我们证明，最轻的右中微子是可能的暗物质候选者，其质量为$ \ mathcal {o}（10）〜\ mathrm {Mev} $，通过谐振冻结场景。探索了暗物质生产，并从各种实验和SM方面的角度的角度讨论了可用的参数空间。
The super-weak model is a U(1) extension of the Standard Model. In addition to a mediator $Z'$, a singlet scalar field $χ$ is added to deal with the meta-stability of the SM vacuum, and right-handed neutrinos are introduced to account for the non-vanishing neutrino masses. We demonstrate that the lightest right-handed neutrino is a possible dark matter candidate with masses of $\mathcal{O}(10)~\mathrm{MeV}$ via the resonant freeze-out scenario. The dark matter production is explored and the available parameter space is discussed from the point of view of various experiments and beyond SM aspects.
