摘要
我们证明，在一个多希格斯模型中，若一个希格斯玻色子与LHC 125 GeV态吻合，则一个或多个其他希格斯玻色子可以介导暗物质-核子相互作用，且对于适当的希格斯-夸克耦合，最大暗物质等旋破缺是可能的，这与暗物质的本质无关。随后我们考虑了II型双希格斯二重态模型的具体实例，将 h 或 H 识别为125 GeV态，而 H 或 h 分别介导暗物质-核子相互作用。最后，我们证明若加入一个稳定标量 S，则它可以是一个具有正确遗迹密度的轻暗物质候选粒子，同时遵守所有直接和间接探测限制。

备注
Two subsections are added to address the collider bounds from direct search for heavy Higgs bosons and from jet plus missing energy final states. The LUX (2013) bound considered in the previous version is replaced by the latest LUX (2016) bound and the SuperCDMS limit is taken into account. The conclusions remain unchanged. A very minor change made in the title and new references included
