Photon–photon scattering


In this paper, we will aim to calculate analytically the one-loop helicity scattering amplitude and differential cross section for the process γγ→ γγ. The computation of this process takes into account non-zero mass of loop-fermion. In certain kinematic limits, compact analytic expressions exist and can be quickly obtained. We present the covariant and helicity amplitudes for this process

Keywords: gauge Models, electroweak interaction, electric charge, photon.
