Abstract

Abstract We consider generic N=1 supersymmetric matter coupled to linearized N=1 supergravity through the multiplet of currents. By completing the square, we find the effective action giving the leading supergravity induced correction to the matter dynamics, expressed explicitly as a quadratic form in the components of the current multiplet. The effective action is supersymmetry invariant through an interplay of the local terms arising from the auxiliary field couplings, and the nonlocal terms arising from graviton and gravitino exchange, neither of which is separately invariant. Having an explicit form for the supergravity induced effective action is a first step in studying effects of supergravity corrections on dynamical supersymmetry breaking and condensate formation in supersymmetric matter dynamics. In the Appendixes we give explicit expressions for the currents, in our notational conventions, in the Wess–Zumino and supersymmetric Yang–Mills models.
