Classical gravitational scattering at O $$ mathcal{O} $$ (G 3) from Feynman diagrams
Abstract We perform a Feynman diagram calculation of the two-loop scattering amplitude for gravitationally interacting massive particles in the classical limit.Conveniently, we are Bicycle Accessories able to sidestep the most taxing diagrams by exploiting the test-particle limit in which the system is fully characterized by a particle propagating
