Abstract

A new N=2 supergravity model is presented, it is exceptional in the sense that it is not described by the usual tensor calculus. It has flat (i.e., identically vanishing) scalar potential and partial breaking to N=1 supersymmetry (γ=0). Our construction is based on a suitable "contraction" of standard Ads supergravity models with matter. The procedure to obtain flat models with hierarchical supersymmetry breakings is also given.
