K* Λ(1116) Photoproduction and Nucleon Resonances
Abstract
We study the reaction mechanism of K* Λ(1116) photoproduction off the proton target near threshold considering the contributions from nucleon-resonances. Employing the effective Lagrangian method at the tree-level Born approximation, we investigate the role of the D 13(2080) and the D 15(2200). We found that the D 13 plays a crucial role to reproduce the experimental data well in the forward scattering region at low energy. We also present theoretical predictions on the single photon-beam asymmetry (Σ) as well as the energy and angular dependence for the cross sections of this reaction.
