Comment on “Non-Velocity Redshifts and Photon-Photon Interactions”

Abstract

IT has been claimed recently1 that some redshifts can be explained by considering a new type of process in which the incident photon scatters inelastically on the 3K radiation to give four less energetic photons. The Lagrangian responsible for the interaction is taken as Λ(AμAμ)2 and the process is considered in the second order only to account for the necessary strong peaking of the cross-section (see Fig. 1). Here we describe the detailed calculation of this process.
