  We study photoproduction of rho mesons in a model of hidden local symmetry.
The rho meson is introduced as a hidden gauge boson and a phenomenological rho
meson-nucleon Lagrangian is constructed respecting chiral symmetry. It is shown
that the sigma exchange interaction is needed for neutral rho meson
photoproduction to reproduce the experimental cross sections. For charged rho
meson photoproduction, the model takes into account the rho meson magnetic
moments from the three-point vertex in the kinetic terms. We show that the
magnetic moment of the charged rho meson has a significant effect on the total
cross sections through the 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.
