Study of Photon Emission at High Temperature of Quark Gluon Interaction

In this paper, the photons emission rate from the interaction of quark with gluon is calculated and studied based on quantum chromodynamics theory. The photonic rate is calculated for u g→d g γ system at bremsstrahlung processes with Bag constant B 1/4 =0.235GeV and B 1/4 =0.275GeV, system temperature (325-625) MeV and the value of fugacity of quark λ Q =0.9 and gluon λ G =0.02 to emit photons with energy 0.5 ≤ E γ ≤ 5GeV in hadronic phase. The effect of system temperature on the photons emission rate was studied and discussed, it was found that it increases with increases of system temperature and decreases of coupling strength due to the deconfinement phenomena furthermore the photonic yield at B 1/4 =0.235GeV is less than the photonic yield at B 1/4 =0.275GeV.
