Off-shell effects in the electromagnetic production of strangeness

Abstract : Previous approaches to the photo- and electro-production of strangeness off the proton, based upon effective hadronic Lagrangians, are extended here to incorporate the so called off-shell effects inherent to the fermions with spin = 3/2. A formalism for intermediate-state, spin 3/2, nucleonic and hyperonic resonances is presented and applied to the processes $\gamma + p ---> K^{+} + as well as the branching ratio for the crossed channel reaction$K^- + p ---> significant, of various observables to such effects are discussed.
