Zusammenfassung:
The path integral for the gravity sector of supergravity, i.e., after integration over the spin-3/2 field, is formally shown to be governed by the linearized Einstein action in terms of redefined field variables. The exponential of the action now being a product of gaussians, positivity of the action in euclidean signature is simply achieved by analytic continuation in those field components whose squares initially appear with the wrong sign.
