Electroproduction of kaons from the proton in a Regge-plus-resonance approach

Understand

We present a Regge-plus-resonance (RPR) description of the p(e,e'K^+)Y processes (Y=\Lambda,\Sigma^0) in the resonance region.

• The background contributions to the RPR amplitude are constrained by the high-energy p(\gamma, K^+)Y data.
• As a result, the number of free model parameters in the resonance region is considerably reduced compared to typical effective-Lagrangian approaches.
• We compare a selection of RPR model variants, originally constructed to describe $KY$ photoproduction, with the world electroproduction database.
