A Bayesian analysis of the world’s (γ, K+)Λ data is presented. We adopt a Regge-plus-resonance framework featuring consistent couplings for nucleon resonances up to spin J = 5/2, and evaluate 2048 model variants considering all possible combinations of 11 candidate resonances. The best model, labeled RPR-2011, is discussed with special emphasis on nucleon resonances in the 1900-MeV mass region.
