The Classical Gravitational Impulse at High Energies
Michael Saavedra
We compute the gravitational impulse for two classical massive scalars in the ultrarelativistic limit to all orders in Newton's constant at fixed to .…
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…
A Systematic Lagrangian Formulation for Quantum and Classical Gravity at High Energies
Ira Z. Rothstein, Michael Saavedra
We derive a systematic Lagrangian approach for quantum gravity in the super-Planckian limit where . The action can be used to calculate to arbitrary accuracy in…
Relations Between Anomalous Dimensions in the Regge Limit
Ira Z. Rothstein, Michael Saavedra
We extend the recent formalism developed for computing rapidity anomalous dimension of form factors using unitarity to the problem of high-energy near forward scattering. By combin…
