  Cosmological inflation models with modifications to include recent
cosmological observations has been an active area of research after WMAP 3
results, which have given us information about the composition of dark matter,
normal matter and dark energy and the anisotropy at the 300,000 years horizon
with high precision.
  We work on inflation models of Guth and Linde and modify them by introducing
a doublet scalar field to give normal matter particles and their supersymmetric
partners which result in normal and dark matter of our universe. We include the
cosmological constant term as the vaccuum expectation value of the stress
energy tensor, as the dark energy. We callibrate the parameters of our model
using recent observations of density fluctuations. We develop a model which
consistently fits with the recent observations.
