Abstract

Unified models based on N = 1 Supergravity possess the novel feature that the spontaneous breaking of SU(2) x U(1) is triggered by the spontaneous breaking of Supergravity. This phenomenon relates the mass scale of the two breakings i.e., one finds the gravitino mass m/sub 9/ approx. M/sub W/, thus establishing a link between the gravitational and the electro-weak interactions. The N = 1 Supergravity unified models predict a variety of new phenomena in the low energy domain and we discuss some of these in the following.
