Abstract

Kaon photoproduction process γp → K+Λ has been analyzed by using the multipole approach. The present analysis provides an update to our previous model. All nucleon resonances listed in the Particle Data Book, with at least two-star rating, are included in the present model. To construct the background amplitudes we use the Feynman diagram-matic technique, whereas for the resonance amplitudes we exploit the Breit-Wigner formulation. The coupling constants in the background part and the helicity photon couplings in the resonance part are extracted by fitting to around 7400 experimental data points. The results are compared with the previous covariant isobar model, Kaon-Maid, as well as the experimental data. It is found that the present model provides a better agreement with the experimental data.
