Inflatonic Q-ball evaporation: A new paradigm for reheating the Universe

摘要: We show that the inflaton condensate associated with a global symmetry can fragment into quasi stable Q balls after end of inflation, provided oscillations give rise to an effective equation state negative pressure. argue chaotic inflation running mass may desired scenario where process fragmentation inflatonic actually take place even though there is total zero charge. such will reheat Universe sufficiently low temperature via surface evaporation.
