The Regge-plus-resonance model for kaon production on the proton and the   neutron
  The Regge-plus-resonance (RPR) framework for kaon photoproduction on the proton and the neutron is an economical single-channel model with very few parameters. Not only does the RPR model allow one to extract resonance information from the data, it has predictive power. As an example we show that the RPR model makes fair predictions for the $p(e,e'K^{+})\Lambda$ and the $n(\gamma,K^{+})\Sigma ^{-}$ observables starting from amplitudes optimized for the reaction $p(\gamma, K ^{+})\Lambda$ and $p(\gamma,K^{+})\Sigma ^{0}$ respectively.
