论文摘要
研究了一类手性仪表理论，并用意外稳定的伪nambu-goldstone玻色子发挥了暗物质（DM）的作用。量规组包含一个类似矢量的深色因子，该因子限制在大于electroweak量表的能量上，以及一个$ {\ rm u}（1）_d $因子，该因子仍然微弱地耦合并且自发损坏。所有新量表都是动态生成的，包括DM质量，IR动力学是完全可计算的。我们分析了这种最小模型，黑暗的费米子将标准模型（SM）仪表组的非平凡矢量样表示转化为。在现实的模型中，DM候选人是SM Singlet，并带有带电的合作伙伴，可以在高能量的乘客中发现。因此，最低的新状态的现象学的特征是天体物理观察和实验室实验的相关预测。
A class of chiral gauge theories is studied with accidentally-stable pseudo Nambu-Goldstone bosons playing the role of dark matter (DM). The gauge group contains a vector-like dark color factor that confines at energies larger than the electroweak scale, and a ${\rm U}(1)_D$ factor that remains weakly coupled and is spontaneously broken. All new scales are generated dynamically, including the DM mass, and the IR dynamics is fully calculable. We analyze minimal models of this kind with dark fermions transforming as non-trivial vector-like representations of the Standard Model (SM) gauge group. In realistic models, the DM candidate is a SM singlet and comes along with charged partners that can be discovered at high-energy colliders. The phenomenology of the lowest-lying new states is thus characterized by correlated predictions for astrophysical observations and laboratory experiments.
