Recent Achievement in Regge Theory for Photoproduction of Hadron Applications
Recent breakthrough in Regge theory explores photoproduction of hadrons, applying the Regge model to understand scaling with trajectory saturation. The study delves into reaction mechanisms at high energies, introducing gauge and tensor meson exchanges. Analysis includes convergence and dominance of tensor mesons, photoproduction at varying energy levels, EM multipoles in the resonance region, and extension schemes of the Regge model. Significant findings on the constituents counting rule, phenomena in the scaled region, and scaling of cross-sections are discussed. This research offers valuable insights into describing hadron reactions and high-energy data.

Summary and Outlook + + p We have studied photoproduction of in the Reggeized model. Reaction cross section at high energies are investigated based on minimal gauge and role of tensor meson . Scaling of differential cross section is analyzed with the saturated trajectory. Powerful model to describe hadron reactions and high energy data from 12 GeV-upgrade at Jlab. But, uncertainties are there in saturation to be improved in future studies. a 2
