The centers of discrete groups as stabilizers of dark matter
Abstract The most usual option to stabilize dark matter (DM) is a $\mathbb {Z}_2$ symmetry. In general, though, DM may be stabilized by any $\mathbb {Z}_N$ with N ≥ 2. We consider the way that $\mathbb {Z}_N$ is a subgroup of the internal-symmetry group G of a model; we entertain …
