Massive gravitino scattering amplitudes and the unitarity cutoff of the new Fayet-Iliopoulos terms
Abstract We compute the 2 → 2 gravitino scattering amplitudes at tree level in supergravity theories where supersymmetry is spontaneously broken. In the unitary gauge, the gravitino becomes massive (of mass m 3/2) by absorbing the Goldstino, and the scattering amplitudes of its longitudinal polarisa...
