First a detailed analysis is made of a broad class of O'Raifeartaigh models coupled to N = 1 supergravity with supersymmetry broken at an intermediate scale. These models can be considered either as an extension of the so called hidden sector models, or as an extension of previously proposed globally supersymmetric models to include the effects of gravity. The process of spontaneous compactification is discussed next and it is applied to two different theories. First, gauged N = 2D = 7 supergravity is considered. Then a general analysis is made for the possible compactification of chiral N = 2D = 10 supergravity (which is the zero mass limit of the type IIB superstring theory) down to four dimensions. Finally the low-energy D = 4N = 1 supergravity that arises after compactification of the E/sub 8/xE/sub 8/ superstring for an arbitrary number of generations is constructed. The couplings of all massless modes that carry low energy gauge quantum numbers are calculated by truncating the heavy Kaluza-Klein modes of the ten-dimensional effective action compatible with the symmetries of the underlying ten-dimensional field (and string) theories.
