Abstract

A constituent quark model is developed for the reaction, allowing us to investigate all available data for differential cross sections as well as single polarization asymmetries (beam and target) by including \it all of the PDG, one to four star, nucleon resonances (S₁₁, P₁₁, P₁₃, D₁₃, D₁₅, F₁₅, F₁₇, G₁₇, G₁₉, H₁₉, I_1,11, and K_1,13). Issues related to the missing resonances are also briefly discussed by examining possible contributions from several new resonances (S₁₁, P₁₁, P₁₃, D₁₃, D₁₅, and H_1,11).
