| Abstract: | We consider the production sources of prompt and thermal photons which include the contribution of gluons in relativistic heavy ion collisions.Considering in our calculation the shadowing and iso-spin effects of the nucleus we can properly estimate the prompt photon production.We develop a new thermal jet-photon conversion mechanism which plays a vital role in the low transverse momentum region.The effect of the non-equilibrium quark-gluon plasma enhances the contribution of thermal photons. |
