Abstract

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(m12 + m12) 1 2, where m1,2 are the masses of the smuons. © 1985.
