Nucleon and $\Delta$ resonances in $\gamma p\to K^{+}{\Sigma }^0(1385)$ photoproduction

Abstract

The photoproduction of $\gamma p\to K^{+}{\Sigma }^0(1385)$ is investigated based on an effective Lagrangian approach using the tree-level Born approximation, with the purpose of understanding the reaction mechanisms and resonance contents and their associated parameters in this reaction. In addition to the $t$-channel $K$ and $K^{\ast }(892)$ exchanges, $s$-channel nucleon ($N$) exchange, $u$-channel $\Lambda$ exchange, and generalized contact term, the exchanges of a minimum number of $N$ and $\Delta$ resonances in the $s$ channel are taken into account in constructing the reaction amplitudes to describe the experimental data. It is found that the most recent differential cross-section data from the CLAS Collaboration can be well reproduced by including one of the $N(1895){1/2}^{-}$, $\Delta (1900){1/2}^{-}$, and $\Delta (1930){5/2}^{-}$ resonances. The reaction mechanisms of $\gamma p\to K^{+}{\Sigma }^0(1385)$ are discussed in detail, and the predictions of the beam and target asymmetries for this reaction are given. The cross sections of $\gamma p\to K^0{\Sigma }^{+}(1385)$ are shown to be able to further constrain the theoretical models and pin down the resonance contents for $\gamma p\to K^{+}{\Sigma }^0(1385)$.
