Slightly ultra-violet freeze-in a hidden gluonic sector
The dark glueball (DGB) from a hidden Yang-Mills sector is a simple non-WIMP dark matter candidate characterized by very few parameters. However, it suffers from the overdensity problem. To overcome it, in general the dark sector is required to be hierarchically cooler than the visible sector. To na...
