Analytic structure of the high-energy gravitational amplitude: multi-H diagrams and classical 5PM logarithms
Francesco Alessio, Vittorio Del Duca, Riccardo Gonzo +3
We investigate the high-energy, small-angle limit of two-body gravitational scattering. Using power counting arguments and dispersion relations in an effective field theory for the…
Searching for Kerr in string amplitudes
Francesco Alessio, Paolo Di Vecchia, Maurizio Firrotta +1
We continue the approach of [1] to attempt to reproduce the classical electromagnetic current of the solution from the infinite-spin limit of a three-point a…
Dirac brackets for classical radiative observables
Francesco Alessio, Riccardo Gonzo, Canxin Shi
We introduce a new coherent state expansion of the exponential representation of the S-matrix for the classical gravitational two-body problem. By combining the Kosower-Maybee-O'Co…
