Regge Model with Scale-Invariance for Nucleon Compton Scattering, Electroproduction, and Electron-Positron Annihilation

A Regge model satisfying the requirement of scale invariance is constructed for the Compton amplitude. Using the P, P′, and A2 Regge trajectories, we obtain good fits to the total photon-nucleon cross sections and to the differential cross section dσdt for proton Compton scattering. The model is then applied to electroproduction in the deep-inelastic region and successfully describes the data on the proton and neutron structure functions, the …
