Mixed inflaton and curvaton perturbations

  title={Mixed inflaton and curvaton perturbations},
  author={David Langlois and Filippo Vernizzi},
A recent variant of the inflationary paradigm is that the “primordial” curvature perturbations come from quantum fluctuations of a scalar field, subdominant and effectively massless during inflation, called the “curvaton”, instead of the fluctuations of the inflaton field. We consider a cosmological scenario which mixes the standard and variant versions, i.e. where primordial curvature perturbations are generated by quantum fluctuations of both an inflaton and a curvaton field. This is the case… CONTINUE READING
