Classical supersymmetric matter and cosmology

We show that supersymmetry may play an important role in giving a reasonable explanation of relevant cosmological features. We work in a classical N=1 supergravity scenario showing that supersymmetric matter leads, in the classical limit, to a fluid model acting as the source of the gravitational fi...
