Effective-Photon Theory: A Critical Analysis
D. Eimerl · Physical Review Letters · 1977
It is shown that effective-photon theory is in serious conflict with established experimental results in two areas. A lower limit on the total photon-photon scattering cross section is derived which requires this cross section to be unacceptably large. The rate of beam degradation also is examined and shown to be too high by many orders of magnitude.
