Progress in kaon photoproduction off the nucleon in six isospin channels

Motivated by the recent abundant experimental data obtained from the continuous and heavy duty accelerators along with the precise and modern particle detectors, we have intensively analyzed the elementary kaon photoproduction processes from their production thresholds up to W ≈ 3 GeV in the last two decades. All possible isospin channels are considered in the analysis because recently experimental data have been available in all channels. This includes γp → K⁺Λ, K⁺ς⁰, K⁰ς⁺ processes off the proton and γn → K⁰Λ, K⁺ς^-, K⁰ς⁰ processes off the neuron. In this proceedings paper we briefly report on the latest progress of our analysis. There are two approaches that have been used for this purpose, i.e., the isobar model which is based on the Effective Lagrangian Theory and the partial wave analysis, in which the corresponding multipoles are parameterized by means of the Breit-Wigner form.
