Abstract：
Photon radiation and dilepton production induced by mutiple parton rescattering are investigated when a hard parton jet produced in relativistic high energy heavy ion collision pass through strong interaction medium. We derive the transverse momentum spectrum and parton energy loss for the radiated photon, the invariant mass spectrum of dilepton. The numerical results turn out: the photon yield decreases as increasing transverse momentum, the dilepton yield decreases as increasing invariant mass. Parton energy loss due to photon radiation depends linearly on thickness of medium targets.
