In the light of recent experimental observation of the radiation amplitude zero (RAZ) in W\gamma production by CDF at Fermilab, we consider its consequences. is the RAZ unique to the standard model? Although it is not for neutrino-electron scattering, in the case of d-ubar scattering which is the case of experimental interest, observation of the RAZ implies that the SM must be correct.
