我们表明，一个新的规范群与一个新的标量导致自动稳定的暗物质候选人。我们考虑希格斯相与受限相对偶的理论：已知SU（2）规范理论与标量偶态（如标准模型）服从这个非平凡的特征。我们给出了一个一般的判据，表明这种自对偶性对SU（N）、SO（N）、Sp（N）和G2规范动力学都成立，它们都是在基本表象中用标量场表示的。由此产生的暗物质现象学具有非平凡的特征，这些特征是该群体的特征，我们将逐案讨论。仅举几例，SU（N）有一个偶然的保守的暗重子数，SO（2N + 1）由于特殊的宇称而导致稳定的胶球，G2导致类似于中性K介子的暗物质系统。宇宙学上的暗物质丰度通常在100 TeV左右的质量下重现：所有的约束都得到满足，较轻的暗胶球可以影响希格斯物理。这些理论获得了额外的兴趣和预测性，假设暗和弱尺度都是动态生成的。
We show that a new gauge group with one new scalar leads to automatically stable Dark Matter candidates. We consider theories where the Higgs phase is dual to the confined phase: it is known that SU (2) gauge theories with a scalar doublet (like the Standard Model) obey this non-trivial feature. We provide a general criterion, showing that this self-duality holds for SU(N), SO(N), Sp(N) and G2 gauge dynamics with a scalar field in the fundamental representation. The resulting Dark Matter phenomenology has non- trivial features that are characteristic of the group, and that we discuss case by case. Just to mention a few, SU(N) has an accidental conserved dark baryon number, SO (2N + 1) leads to stable glue-balls thanks to a special parity, G2 leads to a Dark Matter system analogous to neutral kaons. The cosmological Dark Matter abundance is often reproduced for masses around 100 TeV: all constraints are satisfied and lighter dark glue-balls can affect Higgs physics. These theories acquire additional interest and predictivity assuming that both the dark and weak scales are dynamically generated.
