Gravitino Interactions from Yang-Mills Theory
arXiv:1002.2279 · doi:10.1103/PhysRevD.81.105009
Abstract
We fabricate gravitino vertex interactions using as only input on-shell Yang-Mills amplitudes and the Kawai-Lewellen-Tye gauge theory / gravity relations. A useful result of this analysis is simpler tree-level Feynman rules for gravitino scattering than in traditional gauges. All results are explicitly verified until five point scattering.
