Simple Scenario of Photons Emission from Anti Charm –Gluon Interaction Using QCD Theory
Keywords:Photons Emission, Anti Charm, Gluon, QCD Theory
In this work, the chromodynamics (QCD) theory was used to investigate the photon rate which was produced in interactions of anti-charm with gluon. The simple quantum scenario theory was implemented to give the rate equation that describes the collision of quark and gluon at a chemical potential .The photon emission rate was evaluated from the anti-charm-gluon interaction of the cg → dγ collision at the temperature of the system in the range of 180 - 360 MeV with different critical temperatures (e.g. 116.575, 139.891, 157.377 and 174.863 MeV) with photons energy GeV under the assumption that fugacity of quark and gluon are =0.08 and =0.02 respectively . The photon rate increases with decreasing the coupling of quark and gluon according to a decrease in the temperature of the system from 360 MeV to 180 MeV. The photon emission spectrum was calculated and discussed using a photon energy of 1GeV to 10GeV with different critical temperatures. In terms of QCD theory, the quantitative accomplishment was made for a unique six-flavor number nf = 4 + 2 of photon emission. The photon rate reaches minimum with photon energy E=10 GeV, it reﬂects the less coupling for the cg → dγ interaction.
