摘要

在QCD真空的平均场方法的框架下，讨论了由胶子转换为γ产生光子的具体机制。在限制阶段，由于限制真空场的统计系综的随机取向，胶子产生光子的概率消失。相反，在去约束阶段违反了Furry定理的条件，因此胶子的转换概率为非零，光子分布具有很强的角各向异性。因此，在所研究的过程中产生的光子可以作为夸克胶子等离子体向去约束相转变的重要探针之一。

Photons as Probes of Deconfinement in Quark-Gluon Plasma

The specific mechanism of photon production by conversion from gluons \(gg \to \gamma \) in the framework of the mean-field approach to the QCD vacuum is discussed. In the confinement phase, the production probability of gluons into a photon vanishes due to the random orientation of the statistical ensemble of confining vacuum fields. In contrast, the conditions of Furry theorem are violated in the deconfinement phase, as a consequence—the conversion probability of gluons is nonzero, and photon distribution has a strong angular anisotropy. Thus, the photon production in the investigated process can act as one of the important probes of transition in quark-gluon plasma to the deconfinement phase.
