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 (S11S_{11}, P11P_{11}, P13P_{13}, D13D_{13}, D15D_{15}, F15F_{15}, F17F_{17}, G17G_{17}, G19G_{19}, H19H_{19}, I1,11I_{1,11}, and K1,13K_{1,13}). Issues related to the missing resonances are also briefly discussed by examining possible contributions from several new resonances (S11S_{11}, P11P_{11}, P13P_{13}, D13D_{13}, D15 D_{15}, and H1,11H_{1,11}).
