Abstract

We calculate the photoproduction processes of light vector meson(ρ, ω and Φ) in heavy ion collisions. Based on the narrow-width approximation, we rigorously derive the exclusive and inclusive cross sections of ρ, ω and Φ produced by the semielastic and inelastic photoproduction processes in relativistic heavy ion collisions. The numerical results indicate that contribution of photoproduction processes of light vector meson is not prominent for p-p collisions, but thecontribution becomes evident for p_T >2.5 GeV in Au-Au collisions and p_T >3 GeV in Pb-Pb collisions.
