## Contribution

It introduces a Reggeized approach to model $K ext{Sigma}^*(1385)$ photoproduction, employing a gauge-preserving formalism and coupling constants derived from symmetry and duality principles.

## Key findings

- Reproduces experimental data for $ ext{γ}p$ and $ ext{γ}n$ channels.
- Identifies the dominance of contact term and $K$ exchange in the production mechanism.
- Highlights the role of $K_2^*$ following rather than leading over $K^*$.

## Abstract

Photoproduction of $ K\Sigma^{*}(1385)$ on the nucleon is investigated within the Regge framework and the reaction mechanism is analyzed based on the data existing in the channels $\gamma p\to K^+\Sigma^{*0}$ and $\gamma n\to K^+\Sigma^{*-}$. The Reggeization of the $t$-channel meson exchanges $K(494)+K^*(892)+K_2^*(1430)$ is employed to construct the photoproduction amplitude. The Rarita-Schwinger formalism is applied for the spin-3/2$^+$ strangeness-baryon $\Sigma^*$ 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 $K^*$ and from the duality and vector dominance for the $K_2^*$, 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 $K_2^*$ following rather than the $K^*$.
