Theoretical study of the photons rate production in the Quark-Gluon interaction at Compton scattering

الملخص EN

The aim of this paper is studying and calculation the photons rate emission in quark gluon systems at Compton scattering processes according to the quantum field theory and quantum consideration.

Quantum chromodynamic theory have been used to calculate the photon rate in ug → d? and cg → d? systems at Compton scattering due to the critical temperature T? ? 160 MeV with flavor number ?? ? 3 and 6 and thermal energies T= 150MeV, 200MeV, 250MeV and 300 MeV.

Photons rate is calculated depending on the estimation of the effective strength coupling α???, quantum electrodynamic constant α, photons energy E???? , square charge of the quarks e??? ? , thermal energy T and Euler constant θ????? parameters using a MATLAB designed program.

In both ug → dγ and cg → dγ systems, the rate of photons production are increases with decreases the effective coupling strength and increases thermal energy for one-loop predictions.
