Long-Wavelength Modes of Cosmological Scalar Fields
arXiv:hep-ph/0510009 · doi:10.1103/PhysRevD.73.123514
Abstract
We give a numerical analysis of long-wavelength modes in the WKB approximation of cosmological scalar fields coupled to gravity via . Massless fields are coupled conformally at . Conformality can be preserved for fields of nonzero mass by shifting . We discuss implications for density perturbations.
