Photoproduction of $\gamma N\to K^{+}{\Sigma }^{\ast }(1385)$ in the Reggeized framework

Abstract

Photoproduction of $K{\Sigma }^{\ast }(1385)$ on the nucleon is investigated within the Regge framework and the reaction mechanism is analyzed based on the data existing in the channels $\gamma p\to K^{+}{\Sigma }^{\ast 0}$ and $\gamma n\to K^{+}{\Sigma }^{\ast -}$. The Reggeization of the $t$-channel meson exchanges $K(494)+K^{\ast }(892)+K_2^{\ast }(1430)$ is employed to construct the photoproduction amplitude. The Rarita-Schwinger formalism is applied for the spin-3/2${}^{+}$ strangeness-baryon ${\Sigma }^{\ast }$ with a special gauge prescription utilized for the convergence of these reaction processes. Within a set of coupling constants determined from the symmetry arguement for the $K$ and $K^{\ast }$ and from the duality and vector dominance for the $K_2^{\ast }$, the data of the both processes are reproduced to a good degree. The production mechanism of these processes are featured by the dominance of the contact term plus the $K$ exchange with the role of the $K_2^{\ast }$ following rather than the $K^{\ast }$.
