An effective Lagrangian approach calibrated with one adjustable parameter from data reproduces cross sections for K3*(1780), K2(1820), K2(1770) and K4*(2045) and predicts sizable forward-peaked production for additional high-orbital kaons in K-p reactions.

abstract
We investigate $\gamma p \to K^{*+} \Lambda$ reaction within a Regge approach. For the gauge invariance of the scattering amplitude, we reggeize the s-channel and contact term amplitudes as well as the $t$-channel amplitude. We obtain the decreasing behavior of the total cross section as the CLAS's preliminary data show. We also calculate spin density matrices, and find clear differences between our Regge model and the previous Feynman (isobar) model.

Production of high-orbital kaon excited states in the $K^{-}p$ reaction
