Abstract

We show that supersymmetry may play an important role in giving a reasonable explanation of relevant cosmological features. We work in a classicalN=1 supergravity scenario showing that supersymmetric matter leads, in the classical limit, to a fluid model acting as the source of the gravitational field. The equation of state arises, in a natural way, as a consequence of the field equations. We study conditions for the matter dominated era and the existence of an inflationary solution. Using upper bounds of several red-shift experimental results we are able to give an estimate of the corresponding Hubble constant.
