AI 中文摘要
我们计算手性不对称夸克胶子等离子体的热光子产生率，估算手性夸克散射的硬贡献，结合硬贡献与前期工作中利用硬热圈微扰论的Braaten-Pisarski方法计算的软贡献，证明总热光子发射率的截断无关性。研究发现，手性不平衡的存在会使热光子发射率整体增强。
英文摘要
We compute the thermal photon production rate from a chirally asymmetric quark gluon plasma. We estimate the hard part from scattering of chiral quarks and demonstrate the cut-off independence of the total thermal photon emission rate. This is achieved by combining the hard with the soft contribution evaluated in our previous work using the Braaten-Pisarski method of hard thermal loop perturbation theory. It is observed that the presence of chiral imbalance leads to an overall enhancement in the emission rate of thermal photons.
