Successful supersymmetric dark matter with thermal over/under-abundance from late decay of a visible sector scalar
We present an explicit model where the decay of an $R$-parity-even scalar $S$ with $\mathcal{O}(\mathrm{TeV})$ mass is the origin of nonthermal dark matter. The correct relic abundance can be produced for both large and small annihilation rates in accordance with the Fermi constraints on the annihilation cross section. This scenario …
