相对论性重离子碰撞中的直接光子产生--理论更新

Direct photon production in relativistic heavy-ion collisions -- a theory update

Charles Gale

摘要:

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,我们报告的进展,在模拟的强子动力学的重离子碰撞使用的混合方法,其中包括IP-粒子,相对论流体动力学,和强子级联组件。我们简要地讨论了“光子流之谜”,然后集中在一个非平衡,强相互作用介质的光子发射理论的最新发展。

英文摘要:

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.
