    Research output: Contribution to journalArticlepeer-review


    We present a spontaneously broken N = 2 supergravity model that reduces, in the flat limit MPlanck → ∞, to a globally supersymmetric N = 2 system with explicit soft supersymmetry breaking terms. These soft terms generate a mass O(Mw) for mirror quarks and leptons, while leaving the physical fermions light, thereby overcoming one of the major obstacles towards the construction of a realistic N = 2 model of elementary interactions.
