Generating the primordial curvature perturbation from inflation

چکیده

The scale–independence of the primordial curvature perturbation suggests that it comes from the vacuum fluctuation during inflation of a light scalar field. This field may be the inflaton, or a different ‘curvaton’ field. The observation of primordial non–gaussianity would be a smoking gun for the curvaton model, while the observation of gravitational waves originating during slow–roll inflation would rule out the model.

Constraints on the primordial curvature perturbation from primordial black holes

We calculate the constraints on the primordial curvature perturbation at the end of inflation from the present day abundance of Primordial Black Holes (PBHs), as a function of the reheat temperature TRH. We first extend recent work on the formation of PBHs on scales which remain within the horizon during inflation and calculate the resulting constraints on the curvature perturbation. We then ev...

Generating the curvature perturbation at the end of inflation

a. Introduction The primordial curvature perturbation ζ exists already a few Hubble times before the observable Universe enters the horizon. Its timeindependent value at that stage sets the initial condition for the subsequent evolution of all perturbations in the scalar and adiabatic mode, which in turn seem to the dominant (perhaps the only) cause of inhomogeneity in the Universe. The curvatu...

Inflationary trispectrum for models with large non-Gaussianities

We compute the leading order contribution to the four-point function of the primordial curvature perturbation in a class of single field models where the inflationary Lagrangian is a general function of the inflaton and its first derivative. This class of models includes string motivated inflationary models such as DBI inflation. We find that the trispectrum for some range of parameters could p...
