Classification of all 3 particle S-matrices quadratic in photons or gravitons
Abstract We explicitly construct every kinematically allowed three particle graviton- graviton-P and photon-photon-P S-matrix in every dimension and for every choice of the little group representation of the massive particle P. We also explicitly construct the spacetime Lagrangian that generates eac...
