论文摘要
我们概述了一个场景，即希格斯和复杂的标量暗物质候选者都出现为伪nambu-goldstone玻色子，即打破全球$（7）$对称为$ so（6）$。我们建筑的新颖性是，标准模型Top-Quark的对称合作伙伴是在隐藏的颜色组下收取的，而不是通常的$ su（3）_c $。因此，自发对称性断裂和顶级伙伴的质量的规模可能明显低于具有彩色顶级伴侣的人。立即采取这些量表使模型更加自然，还减少了希格斯和暗物质之间的诱导的非衍生耦合。实际上，这种结构的自然实现描述了简单的热w imd暗物质，该暗物质在全球$ u（1）_d $对称性下是稳定的。我们展示了大型强子对撞机以及当前和下一代的暗物质实验如何探讨该框架的最自然表现。
We outline a scenario where both the Higgs and a complex scalar dark matter candidate arise as the pseudo-Nambu-Goldstone bosons of breaking a global $SO(7)$ symmetry to $SO(6)$. The novelty of our construction is that the symmetry partners of the Standard Model top-quark are charged under a hidden color group and not the usual $SU(3)_c$. Consequently, the scale of spontaneous symmetry breaking and the masses of the top partners can be significantly lower than those with colored top partners. Taking these scales to be lower at once makes the model more natural and also reduces the induced non-derivative coupling between the Higgs and the dark matter. Indeed, natural realizations of this construction describe simple thermal WIMP dark matter which is stable under a global $U(1)_D$ symmetry. We show how the Large Hadron Collider along with current and next generation dark matter experiments will explore the most natural manifestations of this framework.
