Spontaneous breaking of N = 2 to N = 1 in rigid and local supersymmetric theories

We analyze the relation between rigid and local supersymmetric N = 2 field theories, when half of the supersymmetries are spontaneously broken. In particular, we show that the recently found partial supersymmetry breaking induced by electric and magnetic Fayet-Illipoulos terms in rigid theories can be obtained by a suitable flat limit of previously constructed N = 2 supergravity models with partial super-Higgs in the observable sector.
