Description

We analyze all the available data on differential cross sections, total cross sections, and $K^{\ast }$ spin density matrix elements for $K^{\ast +}{\mathrm{\Sigma }}^0$ and $K^{\ast 0}{\mathrm{\Sigma }}^{+}$ photoproduction off proton in an effective Lagrangian approach. The data are well reproduced, and the contributions from the $s$-channel nucleon resonance and $t$-channel $\kappa$ meson exchange diagrams are discussed.
