Liberated N=1 Supergravity

Abstract

We discuss a new interaction for chiral models in four-dimensional $\mathcal{N}=1$ supergavity. It contains a new arbitrary function in addition to the Kähler potential and superpotential. Its features include linearly realized off-shell supersymmetry, Kähler-Weyl invariance and broken supersymmetry. The corresponding scalar potential is augmented by the arbitrary function which allows freedom in constructing low-energy phenomenological models and inflationary models rooted in supergravity.
