我们建立的模型中，暗物质候选者作为一种新的限制规范力的复合态出现，由于偶然的对称性而稳定。限制到与SU(5)统一相容的可重整化理论，我们发现了13个基于SU(N)规范理论的模型和9个基于SO(N)的模型。我们还描述了其他需要不可重整化交互的模型。这两个规范群导致了不同的现象：SU(N)理论给出了复杂的DM，具有潜在的可观察到的电偶极矩和磁偶极矩，导致特殊的自旋独立截面；因此(N)理论给出了真实的DM，具有挑战性的自旋相关截面或非弹性散射。具有汤川耦合的模型还产生了由希格斯玻色子介导的与自旋无关的直接探测和电子的电偶极矩。在一些型号中，DM具有更高的自旋。每个模型都预测了一组特定的较轻的合成标量，可能在对撞机上可以观察到。
We build models where Dark Matter candidates arise as composite states of a new confining gauge force, stable thanks to accidental symmetries. Restricting to renormalizable theories compatible with SU(5) unification, we find 13 models based on SU(N) gauge theories and 9 based on SO(N). We also describe other models that require non-renormalizable interactions. The two gauge groups lead to distinctive phenomenologies: SU(N) theories give complex DM, with potentially observable electric and magnetic dipole moments that lead to peculiar spin-independent cross sections; SO(N) theories give real DM, with challenging spin-dependent cross sections or inelastic scatterings. Models with Yukawa couplings also give rise to spin-independent direct detection mediated by the Higgs boson and to electric dipole moments for the electron. In some models DM has higher spin. Each model predicts a specific set of lighter composite scalars, possibly observable at colliders.
