Brane inflation: A field theory approach in background supergravity
  We propose a model of inflation in the framework of brane cosmology driven by
background supergravity. Starting from bulk supergravity we construct the
inflaton potential on the brane and employ it to investigate for the
consequences to inflationary paradigm. To this end, we derive the expressions
for the important parameters in brane inflation, which are somewhat different
from their counterparts in standard cosmology, using the one loop radiative
corrected potential. We further estimate the observable parameters and find
them to fit well with recent observational data. We have studied extensively
reheating phenomenology, which explains the thermal history of the universe and
leptogenesis through the production of thermal gravitino pertaining to the
particle physics phenomenology of the early universe.
