12. 5)} together with a combinatorial factor of 20. Contracting the W fields using the large mass limit of the W propagator and Fierz rearranging the weak currents gives 4 times the usual expression for the photon-photon scattering amplitude with one photon field replaced by the neutrino current. In addition, there is a term with one axial vector current, which vanishes by Furry's theorem. Equation (1) then follows. For another discussion, see A. Abada, J. Matias, and R. Pittau, hep-ph/9806383 (1998).
