Thermal dark matter from a highly decoupled sector
Thermal dark matter from a highly decoupled sector
It has recently been shown that if the dark matter is in thermal equilibrium with a sector that is highly decoupled from the Standard Model, it can freeze out with an acceptable relic abundance, even if the dark matter is as heavy as $\ensuremath{\sim}1--100\text{ }\text{ }\mathrm{PeV}$. In such scenarios, both …
