Spontaneous symmetry breaking in N=2 supergravity

Abstract

A model describing the $N=2$ supergravity interaction with vector and linear multiplets is constructed. It admits the introduction of the spontaneous breaking of supersymmetry with arbitrary scales, one of which may be equal to zero, which corresponds to partial super-Higgs effect ($N=2 \rightarrow N=1$). A cosmological term is automatically equal to zero.
