The Inflationary Energy Scale in Braneworld Cosmology
arXiv:astro-ph/0306311 · doi:10.1103/PhysRevD.68.083505
Abstract
Upper bounds on the energy scale at the end of inflation in the Randall-Sundrum type II braneworld scenario are derived. The analysis is made exact by introducing new parameters that represent extensions of the Hubble flow parameters. Only very weak assumptions about the form of the inflaton potential are made. In the high energy and slow roll regime the bounds depend on the amplitude of gravitational waves produced during inflation and become stronger as this amplitude increases.
