High energy pion photoproduction amplitudes from fixed-t dispersion relations and duality
Contributions to the high energy imaginary parts of the charged and neutral pion photoproduction amplitudes from degenerate rho and A/sub 2/ exchanges and omega and B exchanges are parametrized similarly to the dual absorptive model. These contributions together with the imaginary parts of the ampli...
