Photon production in relativistic heavy ion collisions with equilibrium and non-equilibrium QGP

  • 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.

Photon production in relativistic heavy ion collisions with equilibrium and non-equilibrium QGP

    Corresponding author: FU Yong-Ping,

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.
