大型强子对撞机实验表明,彩色玻璃凝聚体(CGC)的预测往往低估了中等快度的多重性。我们开发和估计一个完整的二阶粘性流体动力学模型的纵向膨胀,发现CGC快度分布明显变形的流体动力学阶段,由于熵产生和前向快度的熵通量之间的相互作用。结果表明,考虑粘性流体动力学演化与非助推不变流的重离子碰撞中的CGC理解的重要性。
The Large Hadron Collider experiments have revealed that the predictions of the color glass condensate (CGC) tend to underestimate the multiplicity at mid-rapidity. We develop and estimate a full second-order viscous hydrodynamic model for the longitudinal expansion to find that the CGC rapidity distributions are visibly deformed during the hydrodynamic stage due to the interplay between the entropy production and the entropy flux to forward rapidity. The results indicate the importance of considering viscous hydrodynamic evolution with non-boost invariant flow for understanding the CGC in heavy-ion collisions.
