Overview

This research demonstrates new constraints on scattering amplitudes without forward limits, indicating a method robust to radiative corrections.

Key Points

  • This method avoids the Coulomb pole in scattering amplitudes, enhancing robustness in calculations.
  • Constraints on effective field theories are derived using dispersion relations away from the forward limit.
  • Unitarity and analyticity of scattering amplitudes aid in the study of massless particles and gravity.
  • The approach addresses singularities from calculable loop effects, preventing divergence in results.
