摘要：
We calculate the production cross section for dileptons, photons, and light vector mesons (rho, omega, and phi) produced by the photoproduction processes in relativistic heavy ion collisions. The jet-quenching effects for fragmentation processes with p(T) > 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.
