R^2-corrections to Chaotic Inflation
arXiv:gr-qc/0308040 · doi:10.1142/S0217732303011691
Abstract
Scalar density cosmological perturbations, spectral indices and reheating in a chaotic inflationary universe model, in which a higher derivative term is added, are investigated. This term is supposed to play an important role in the early evolution of the Universe, specifically at times closer to the Planck era.
