Abstract: (Elsevier)

We compute the gravitino contribution to ( g − 2) e , μ in the context of spontaneously broken minimal N = 1 supergravity. We show that this contribution is finite and from its value in the limit of a very light gravitino we obtain a phenomenological lower bound for the gravitino mass, m 3 2 > 5.8 × 10 −18 (m 1 2 + m 1 2 ) 1 2 , where m 1,2 are the masses of the smuons.
