标题： Singlet-doublet dark matter revisited

摘要： 单重态-双重态模型是一种弱相互作用暗物质的经济性模型。鉴于暗物质直接探测限制的改进，我们重新审视了该模型。我们描述了那些直接探测截面受到抑制的参数空间中现在已被很好定义的区域，并讨论了在大型强子对撞机上可访问的光谱特征。我们讨论了当从一般的紫外初始条件开始时，这些特殊区域中的参数如何以及何时可能通过重整化群演化实现。 显示英文摘要

摘要： The singlet-doublet model is an economical model of weakly interacting dark matter. We revisit it in light of improved dark matter direct detection limits. We characterize the now well-defined regions of remaining parameter space with suppressed direct detection cross sections and discuss features of the spectrum accessible at the Large Hadron Collider. We discuss when and how parameters in these special regions might be realized as the result of renormalization group evolution when starting with generic ultraviolet initial conditions.
