Models of inflation, supersymmetry breaking and observational constraints

Abstract

We review the connection between inflationary models and observations and concentrate to describe models based on softly broken supersymmetry, in particular running mass models, and their predictions. We then present a fit of the spectral index of the curvature perturbation, assuming a flat $\Lambda$CDM cosmology.
