In its simplest form the curvaton paradigm requires the Hubble parameter during inflation to be bigger than 10 GeV, but this bound may be evaded in non-standard settings. In the heavy curvaton scenario the curvaton mass increases significantly after the end of inflation. We reanalyze the bound in this set up, taking into account the upper bound on the curvaton mass from direct decay. We obtain H∗ > 10 8 GeV if the mass increase occurs at the end of inflation, and H∗ > 10 −14 GeV if it occurs… CONTINUE READING
