dc.description.abstract | To critically compare the Michigan and Argonne models we perform simultaneus fits to the high-energy data for [pi]0 and [nu] photoproduction together with that for the related hadronic vector meson production reactions, in particular that for [pi]+n --> [omega]p. Thus all constraints on these models are considered simultaneously. Particular attention is given to the strength of absoptive cuts in both models, and to the role of the B-meson exchange in filling dips in the Argonne model. We find that the [varrho]-Pomeron cuts (i.e. cuts associated with large helicity flip at the N vertex) are essential to introducing unnatural parity exchange in the Michigan model, and that the B-meson contribution is incapable of filling unwanted dips which appear in any model with nonsense wrong signature zeros as required by exchange degeneracy. The flip and non-flip [varrho] and [omega] coupling strengths at the N vertex are determined. Predictions are made for various polarization asymmetries for [gamma]p --> [pi]0p and [gamma]p --> [eta]p. The differential cross section for KL0p --> KS0p is calculated and compared with the existing data. | en_US |
