We extend to evaluate electromagnetic radiation using modified quark mass from a chemically non-equilibrated quark-gluon plasma with finite baryonic density. In this study, the total photon rate is computed upto two loop processes incorporating parametrization factor in both the quark mass and coupling value. The photon spectrum is obtained by integrating the photon rate over the space-time history of the plasma. The result is found enhancement in the photon emission by the presence of chemical potential and parametrization factor in the quark mass and coupling value. The result shows valuable insights in the measurement of photon production.

“…We have shown the calculated distributions of the temperature T, quark chemical potential µ q , fugacities λ g and λ q along the r direction at z = 0 for µ q0 / T 0 = 1 in figures 1 and 2. We find that the evolution of the present model is much faster than Photons of a chemically equilibrating QGP S849 the one of the one-dimensional model (see [8,16]). We have calculated the photon yield due to the q q → gγ , qg → qγ, qg → qγ , bremsstrahlung and inelastic pair annihilation processes on the basis of the evolutions for initial ratios µ q0 /T 0 = 0.1, 0.5 and 1 [17] (see the left panel of figure 3).…”

We extend to calculate the direct photon production from quark–gluon plasma (QGP) considering finite chemical potential. The calculation is done from a system of strongly interacting QGP and the result is found to be increasing function of chemical potential in all the channels of photon production. It also shows enhancement of photon production from photon production without chemical potential and other theoretical calculation of direct photon productions.
