Nucleon and Delta resonances in K Sigma(1385) photoproduction from nucleons

Abstract

The reaction mechanisms for $K\Sigma (1385)$ photoproduction from the reaction $\gamma p\to K^{+}{\Sigma }^0(1385)$ in the resonance energy region are investigated in a hadronic model. Both contributions from $N$ and $\Delta$ resonances of masses around 2 GeV as given in the Review of Particle Data Group and by the quark model predictions are included. The Lagrangians for describing the decays of these resonances into $K\Sigma (1385)$ are constructed with the coupling constants determined from the decay amplitudes predicted by a quark model. Comparing the resulting total cross section for the reaction $\gamma p\to K^{+}{\Sigma }^0(1385)$ with the preliminary data from the Thomas Jefferson National Accelerator Facility, we find that the most important contributions are from the two-star rated resonances $\Delta (2000)F_{35}$, $\Delta (1940)D_{33}$, and $N(2080)D_{13}$, as well as the missing resonance $N{\frac{3}{2}}^{-}(2095)$ predicted in the quark model. Predictions on the differential cross section and photon asymmetry in this reaction are also given.
