Abstract

For tomographic studies of relativistic nuclear collisions and of the quark-gluon plasma, photons (real and virtual) are unique. They are the only probes than can be both soft and penetrating. First we report on advances in modelling the hadron dynamics of heavy-ion collisions using a hybrid approach which consists of IP-Glasma, relativistic fluid dynamics, and hadronic cascade components. We briefly discuss the "photon flow puzzle", and then focus on a recent development in the theory of photon emission from a non-equilibrium, strongly interacting medium.
相对论重离子碰撞中的直接光子产生——一个理论更新
对于相对论性核碰撞和夸克-胶子等离子体的层析成像研究,光子(实光子和虚光子)是独一无二的。它们是唯一既柔软又有穿透力的探针。首先,我们报告了使用混合方法模拟重离子碰撞的强子动力学的进展,该方法包括IP-Glasma,相对论流体动力学和强子级联组件。我们简要讨论了“光子流难题”,然后重点介绍了非平衡强相互作用介质中光子发射理论的最新进展。
