Lyth, D. H. (2006) Non-Gaussianity and cosmic uncertainty in curvaton-type models. Journal of Cosmology and Astroparticle Physics.Full text not available from this repository.
In curvaton-type models, observable non-Gaussianity of the curvature perturbation would come from a contribution of the form (δσ)2, where δσ is Gaussian. I analyse this situation allowing δσ to be scale dependent. The actual curvaton model is considered in more detail than before, including its cosmic uncertainty and anthropic status. The status of curvaton-type models after WMAP (Wilkinson microwave anisotropy probe) year three data is considered.
