摘　　要：We calculate the production of large transverse momentum dileptons and photons by using direct and resolved photoproduction processes in relativistic heavy ion collisions. Considering the central collisions of heavy nuclei at Relativistic Heavy Ion Collider （RHIC） and Large Hadron Collider （LHC） energies, we find that the photoproduction processes modify the dilepton and photon production in the large transverse momentum region.We calculate the production of large transverse momentum dileptons and photons by using direct and resolved photoproduction processes in relativistic heavy ion collisions.
