Inflaton or Curvaton? Constraints on Bimodal Primordial Spectra from Mixed Perturbations
We consider Cosmic Microwave Background constraints on inflation models for which the primordial power spectrum is a mixture of perturbations generated by inflaton fluctuations and fluctuations in a curvaton field. If future experiments do not detect isocurvature modes or large non-Gaussianity, it w...
