Role of Resonances in the Electromagnetic Production of Kaon Near Threshold

Abstract

Kaon photo- and electroproduction processes near their production thresholds are investigated by using an effective Lagrangian method. It is found that the nucleon and hyperon resonances play a considerably important role in this kinematics. It is also found that kaon photoproduction off the proton may provide a new arena for investigating the existence of the narrow resonance predicted by the soliton models.
