We calculate the production cross section for dileptons, photons, and light vector mesons (ρ, ω, andφ) produced.by the photoproduction processes in relativistic heavy ion collisions. The jet-quenching effects for fragmentation.processes with pT > 2 GeV and the jet-medium interaction with pT > 4 GeV for the fast jets passing through the.quark-gluon plasma in Pb-Pb collisions are also considered. The numerical results of photoproduction processes.can improve the contribution of dileptons, photons, and light vector meson production in p-p and Pb-Pb collisions.at Large Hadron Collider energies.
