Neutral-Meson Production by Gamma-Ray

Abstract:

By means of the Lorentz-covariant perturbation and renormalization methods, the effective cross section for γ-π0 process in pseudoscalar meson theory has been obtained with the matrix elements calculated up to the order ef3. The most conspicuous result, which could not be reached in the lowest order calculation, is that the cross section for neutral meson production turns out to be of the same order as that for charged meson, and that the angular distribution for that process is larger in the forward than in the backward direction. Further we have introduced a Pauli-type interaction with suitably chosen coupling constants in order to estimate the effect of the matrix elements of orders higher then ef3, and gained a result similar to the above one, only with a smaller value for the coupling constant.
