Enhancement in the production of photons from hot and dense matter of quark gluon plasma

In relativistic heavy-ion collisions, photons has long been recognized as a useful deep probe that provide the exact information of quark-gluon plasma (QGP). These photons probe the entire space time evolution of the plasma due to electromagnetic interaction and has large mean free path. Researcher believe that the system is not fully transparent due to massive collision between nuclei and it has some finite value of chemical potential. In this present work, we perform the calculation of leading order processes for photon emission which consist QCD Compton Scattering, qq-bar annihilation, Bremsstrahlung (brems), and annihilation with scattering (aws) from hot and dense matter using quark mass dependent on temperature and quark chemical potential. The results are improved with the effect of quark chemical potential as well as parametrization factor
