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…
Fermi Liquid Fixed Point Deformations due to Codimension Two Defects
Jin-Yun Lin, Ira Z. Rothstein
We show that codimension-two defects in Fermi liquids deform the renormalization group flow via a marginally relevant coupling. The mechanism for generating the flow is distinct fr…
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…
Extracting the Asymptotic Behavior of S-matrix Elements from their Phases
Ira Z. Rothstein, Michael Saavedra
The asymptotic kinematic limits of S-matrices are dominated by large logarithms which, roughly speaking, fall into two categories: those which are controlled by a renormalization g…
