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…

Gravitational amplitudes in the Regge limit: waveforms, shock waves and unitarity cuts

Francesco Alessio, Vittorio Del Duca, Riccardo Gonzo +1

Motivated by recent progress in the high-energy description of gravitational scattering, we develop a systematic Regge-theory framework for amplitudes describing the scat…
