摘要:

热而致密的QCD物质的流动性,是高能重离子碰撞中所产生介质的一个关键特征。我们扩展了相对论流体动力学模型框架,以纳入碰撞系统动力学演化过程中可能出现的非热动量分布。通过数值模拟,阐明了这些修正对对撞机实验中测量的带电强子和直接光子的现象学影响。

英文摘要:

The fluidity of the hot and dense QCD matter is a key characteristic of the medium created in high-energy heavy-ion collisions. We extend the framework of the relativistic hydrodynamic model to incorporate non-thermal momentum distributions that may emerge during the dynamical evolution of the collision system. Numerical simulations are performed to elucidate the phenomenological implications of these modifications on charged hadrons and direct photons measured in collider experiments.
