Classical solutions and their double copy in split signature

Classical solutions and their double copy in split signature

Abstract The three-point amplitude is the key building block in the on-shell approach to scattering amplitudes. We show that the classical objects computed by massive three-point amplitudes in gauge theory and gravity are Newman-Penrose scalars in a split-signature spacetime, where three-point ampli...
