Free light fields can change the predictions of hybrid inflation

Abstract

We show that the free light scalar fields that may exist in the inflationary Universe can change the predictions of the hybrid inflation model. Possible signatures are discussed, which can be used to discriminate the sources of the spectrum.

In conclusions and discussions added a short comment about non-trivial waterfall
