Description

The mechanism of preheating in supersymmetric models of inflation will be introduced in context of existence of flat directions. Flat directions, a typical feature of supersymmetric models, can acquire large vacuum expectation values (VEVs) during inflation. A recent discussion about the impact of such large VEVs on the process of non-perturbative particle production will be presented, signalizing the role of supergravity corrections.
