We consider theories with one gauge group (SU, SO or Sp) and one scalar in a two-index representation. The renormalizable action often has accidental symmetries (such as global U(1) or unusual group parities) that lead to one or more stable states, providing Dark Matter candidates. We discuss the confined phase(s) of each theory and compute the two Higgs phases, finding no generic dualities among them. Discrete gauge symmetries can arise and accidental symmetries can be broken, possibly giving pseudo-Goldstone Dark Matter. Dark Matter candidates can have a complicated sub-structure characteristic of each group and can be accompanied by extra dark radiation.

标量规范动力学和暗物质

我们在双指数表示中考虑具有一个规范群（SU、SO 或 Sp）和一个标量的理论。可重整化动作通常具有偶然的对称性（例如全局 U(1) 或不寻常的组奇偶性），导致一个或多个稳定状态，提供暗物质候选者。我们讨论每个理论的受限相并计算两个希格斯相，发现它们之间没有通用的对偶性。离散规范的对称性可能会出现，偶然的对称性可能会被破坏，可能会产生伪金石暗物质。暗物质候选者可以具有每组复杂的子结构特征，并且可以伴随额外的暗辐射。
