Light Dark Matter from Entropy Dilution

Light Dark Matter from Entropy Dilution

Abstract We show that a thermal relic which decouples from the standard model (SM) plasma while relativistic can be a viable dark matter (DM) candidate, if the decoupling is followed by a period of entropy dilution that heats up the SM, but not the dark sector. Such diluted hot relics can be as ligh...
