摘要

本文基于量子理论,利用夸克-胶子相互作用的QCD动态场景,对光子发射进行了理论研究。通过推导理想量子量子粒子在一定化学势下的光子发射速率方程,实现了量子量子cd理论。在临界温度(132.38,和198.57)MeV和光子能量(GeV)的系统温度下,必须计算g→γ体系中反上胶子相互作用的夸克-胶子相互作用的光子速率。我们研究了临界温度、强度耦合和光子能量对光子速率贡献的显著影响。在这里,我们预测由于系统温度从360 MeV降低到180 MeV,光子发射率增加,夸克-胶子反应的耦合强度降低。给出了(1 ~ 10)GeV范围内的光子能量和4种临界温度下的速率谱。我们的结果中有趣的一点是光子速率的最小值,特别是在光子能量E=10 GeV的flavor中,这反映了g→γ体系中夸克和胶子之间的耦合较差,这是我们已经预料到的。在光子能量E=1 ~ 10 GeV的情况下,获得了QCD结果的特征,并从理论上计算了耦合强度和光介子速率。我们可以注意到,以强子相极限为特征的渐近行为将得到满足。

Theoretical Analysis Of The Photon Production Rate in the Quark-Gluon Interaction According To The Quantum Cromodynamic QCD Theory
           In this work, we have used the QCD dynamic scenario of the quark gluon interaction to investigate and study photon emission theoretically based on quantum theory. The QCD theory is implemented by deriving the photon emission rate equation of the state of ideal QGP at a  chemical potential. The photon rate of the quark-gluon interaction has to be calculated for the anti up-gluon interaction in the g →  γ system at the temperature of system  with critical temperature ( 132.38, ,  and 198.57) MeV and photon energy (  GeV. We investigated a significant effect of critical temperature, strength coupling, and photon energy on the photon rate contribution. Here, the increased photon emission rate and decreased strength coupling of the quark-gluon reaction due to the decrease in temperature of the system from 360 MeV to 180 MeV are predicted. Photon energy in the range (1 to 10) GeV and the rate spectrum of four varieties of critical temperatures are presented.   The interesting point in our results is the minimum value of photon rate, especially in the photon energy E=10 GeV of  flavor which reflects the poor coupling between quark and gluon  in the the g →  γ system which was already expected. The features of QCD  results are  achieved in the case of  flavors for the photon energy E=1 to 10 GeV, the strength coupling and the photo meason rate are calculated theoretically. We can notice that the asymptotic behavior, which was characterized by a hadronic phase limit, will be satisfied.
