Contribution of N* and Δ* Resonances in $${K^*\Sigma}$$ (1190) Photoproduction

Abstract

In this talk, we report theoretical studies on the K * 0 Σ + (1190) photoproduction in the tree-level Born approximation, employing the effective Lagrangian method. We present the energy and angular dependences of the cross sections. It turns out that the N * and ∆ * resonance contributions are negligible in the vicinity of the threshold. On the contrary, we observe that the κ and K exchanges in the t channel and ∆(1232) in the s channel dominate the scattering process, reproducing the experimental data qualitatively well.
