Abstract

We apply implicit regularization in the calculation of the one-loop graviton and gravitino corrections to the anomalous magnetic moment of the lepton in unbroken supergravity. This is an important test for any regularization method. We find a null result as it is expected from supersymmetry. We compare our results with the ones obtained by using differential regularization and dimensional reduction, which are known to preserve supersymmetry at one-loop order.
