论文摘要
由于费米的数量保护，在限制量规理论中以复合状态而产生的光费仪是稳定的。这导致了与基本DM相似的暗物质候选者，但是宇宙学稳定性自动产生的地方是该理论的意外对称性。我们介绍了基于't Hooft异常匹配条件的显式模型，在SM下为DM收取DM。例如，在su（2）$ _ l $的伴奏代表和三胞胎中具有fermions的su（n）仪表理论产生了由多个“ wino”三重态制成的DM，而（n）具有$ n_f = n-4 $ flavors的（n）仪表理论会产生类似Neutinalino的系统或SM Quintuplets。综合效应对于确定现象学至关重要。
Light fermions that arise as composite states in confining gauge theories are stable due to fermion number conservation. This leads to Dark Matter candidates that behave similarly to elementary DM but where the cosmological stability arises automatically from the accidental symmetries of the theory. We present explicit models based on 't Hooft anomaly matching conditions where DM is charged under the SM. For example an SU(N) gauge theory with fermions in the adjoint rep and triplet of SU(2)$_L$ gives rise to DM made of multiple "Wino" triplets, while SO(N) gauge theories with $N_F=N-4$ flavors produce neutralino-like systems or SM quintuplets. Compositeness effects are crucial to determine the phenomenology.
