Abstract :
The photon production from quark-gluon plasma in heavy ion collision is studied using a suitably modified dynamical quark mass depending on non-zero value of quark chemical potential and temperature. The total photon rate is computed for annihilation process ( → γg) and QCD Compton scattering process (qg → qγ) or ( → ) incorporating parameterization factor in both the quark mass and coupling value. Photon spectra are calculated by integrating the production rate over the space-time history of the plasma. It is found that the emission rate to lowest order increases strongly with increasing the quark chemical potential
