Abstract

The purpose of the present discussion is to supplement the talk, by B.~Saghai at this workshop, on the study of the electromagnetic production of strangeness on the nucleon based upon effective Lagrangian methods. Here we focus on the proper treatment of the spin 3/2 resonances and their associated effects due to the spin 1/2 component of the corresponding fields when they are off the mass shell.
