Abstract
We analyze recent meson photoproduction data from the CLAS collaboration for the reactions and , fitting measured forward-angle differential cross sections to the form . We develop a quantitative scheme for determining the kinematic region where the fit is to be done, and, from the extracted -slope , determine whether single-Reggeon exchange can explain the production mechanism. We find that, in the region , production of the channel can be explained by single Reggeon exchange, but the production channel cannot. We verify these conclusions by fitting the data to a differential cross section produced by the interfering sum of two exponential amplitudes.
