Photoproduction of $\gamma N\to K^+ \Sigma^*(1385)$ in the Reggeized framework
Abstract
Photoproduction of on the nucleon is investigated within the Regge framework and the reaction mechanism is analyzed based on the data existing in the channels and . The Reggeization of the -channel meson exchanges is employed to construct the photoproduction amplitude. The Rarita-Schwinger formalism is applied for the spin-3/2 strangeness-baryon 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 and and from the duality and vector dominance for the , 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 exchange with the role of the following rather than the .
