Abstract
Observed enhancements in the forward and backward directions for meson photoproduction off nucleons are shown to be explainable by the production of a nonresonant recoiling diquark, triquark pair. We show that the necessity of maintaining approximate collinearity of the quarks within these units constrains configurations with the minimum momentum transfer, and hence maximal amplitudes, to lie preferentially along the reaction axis.
