Inflaton freeze-out
  We study the possibility that, after inflation, the inflaton reaches thermal
equilibrium with the Standard Model thermal bath and eventually freezes-out in
the non-relativistic regime. When the inflaton decay is the sole source of
(non-thermal) dark matter, its relic density is automatically suppressed. We
delineate parameter space leading to the correct dark matter abundance. The
model allows for a significant Higgs-inflaton coupling which may lead to
invisible Higgs decay into inflaton pairs at the LHC.
