Curvature Perturbation from Supersymmetric Flat Directions
We show that a contribution to the total curvature perturbation may be due to the presence of flat directions in supersymmetric models. It is generated at the first os- cillation of the flat direction condensate when the latter relaxes to the minimum of its potential after the end of inflation. We a...
