Abstract

We have studied two different formulations of spin 3/2 nucleon resonance by means of kaon photoproduction on the proton γp→K+Λ. The formulations of spin 3/2 nucleon resonances proposed by Adelseck (model A) and Pascalutsa (model B) have been used in deriving the scattering amplitudes. The amplitudes are calculated by means of the relevant Feynman diagrams for the process. All nucleon resonances with spin up to 3/2 listed by the Particle Data Group are included in the model. Both formulations are then compared with the experimental data, which include differential cross section and polarization observables, through X2 minimization. It is found that the Pascalutsa's formulation of the spin 3/2 leads to a better agreement with the experimental data.
