A theoretical calculation of thermal photonic rate resulting from quark-gluon collisions

In this paper, the thermal photon rate generated by the interaction between a charm quark beam and a gluon in cg→ugγ plasma is studied using a computational approach. The quantum chromodynamics theory of quark-gluon collisions is used to investigate thermal photon emission. In the theoretical computational approach, quark charge flavour quantum number, strength coupling and thermal photon rate are calculated considering critical energy Tc=160 MeV, thermal energy (200-600) MeV, quark and gluon annihilation, photon energy in the range (0.75-10.25) GeV parameter to calibrate and study the photon rate spectrum. Calculation of the thermal photon rate produced by cg→ugγ from the QGP material consisting of quark-gluon plasma. It was found that in collisions it increases with increasing thermal energy, decreasing coupling strength and decreasing photon energy. The thermal photon rate in cg→ugγ increases slightly to a large at photon energyE≤2 GeV and reach to maximum at E=0.75 GeV compared to reaching a small at energyE≫5 GeV and reaching a minimum at energy=10.25 GeV in cg→ugγ systems.
