Six-Photon Amplitudes in Scalar QED

Abstract

The analytical result for the six-photon helicity amplitudes in scalar QED is presented. To compute the loop, a recently developed method based on multiple cuts is used. The amplitudes for QED and $QE{D}^{\text{caln}=1}$ are also derived using the supersymmetric decomposition linking the three theories.
