| Abstract: | We study the photoproduction of r rho -mesons in a model of hidden local symmetry. For this purpose, the r rho -meson is introduced as a hidden-gauge boson in a non-linear sigma model. For charged r rho -meson photoproduction, the model takes into account the r rho -meson magnetic moments from the three-point vertex in the kinetic terms. We show that the magnetic interaction of the charged r rho -meson has a significant effect on the total cross-sections through the r rho -meson exchange process, which is proportional to the energy of the photon. The t -channel dominance may be used for the study of structures of various unstable particles. |
