Abstract. New isobar models for the photoproduction of kaons off the proton target were constructed utilizing a consistent formalism for exchanges of high-spin resonances and energy-dependent widths of nucleon resonances. For adjusting the free parameters of the model to experimental data we employ reg-ularization techniques, which prevent us from overfitting the data. We analysed the plentiful data on the K+Λ channel as well as the recent data on K+σ− channel and compare the results with data.
