The Inflationary Energy Scale in Braneworld Cosmology
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.Comment: 10 pages, 3 figure
