Chromo-Natural inflation in Supergravity

Abstract

We present supergravity realizations of chromo-natural inflationary models. We show that by using superpotentials with "imaginary" holomorphic functions of the inflaton one can obtain effective theories of inflation that are also consistent truncations of the original supergravity models.

5 pages. v2: References added, consistent truncation clarified and added a paragraph on non-linear realizations
