Holomorphic classical limit for spin effects in gravitational and electromagnetic scattering
Abstract We provide universal expressions for the classical piece of the amplitude given by the graviton/photon exchange between massive particles of arbitrary spin, at both tree and one loop level. In the gravitational case this leads to higher order terms in the post-Newtonian expansion, which hav...
