Abstract

The complete structure of curvature squared terms is analyzed in the context of chirally extended supergravity, with special emphasis on the gravitationally induced Fayet-Iliopoulos D-term. Coupling of (chiral) matter is discussed in relation with a possible extension to (7(1) supergravity of the equivalence mechanism between R + αR² and General Relativity coupled to a scalar. a Unité Propre de Recherche 7061
