摘要
在SPS、RHIC和LHC碰撞能区,利用SU(2)规范对称性,研究了强子物质中介子相互作用产生的热光子.计算结果表明,在SPS能区,强子气体对热光子谱起到更重要的作用,在205 MeV初始温度条件下,强子气体热光子产额比夸克-胶子等离子体的产额高.在RHIC和LHC能区,夸克-胶子等离子体的作用随碰撞能量的增加而逐渐变得重要.
Hot photons from strongly interactions of meson in hadronic matter at SPS, RHIC and LHC collision energy are studied with the gauge theory of SU（2） symmetry. The hadronic gas is found to contribute dominantly for thermal photon spectrum at SPS energy. Hadronic gas has higher thermal photon yield than quark-gluon plasma at temperature of 205 MeV. The contribution of quark-gluon plasma becomes important with increasing of collision energy at RHIC and LHC energy.
