论文摘要
我们报告了相对论理想流体动力学方程的新分析解决方案的发现。在该溶液中，流体在纵向方向上膨胀，并包含一个平稳结构，该平台结构在速度上延伸到有限范围，并且可以在该变量中是对称的或不对称的。我们进一步计算强子产量的相应伪长度分布，并与高能量PB+PB，AU+AU，P+PB和D+AU碰撞中发现相当的一致性。
We report on the discovery of new analytical solutions of the equations of relativistic ideal hydrodynamics. In this solution, the fluid expands in the longitudinal direction and contains a plateau structure that extends over a finite range in rapidity and can be either symmetric or asymmetric in that variable. We further calculate the corresponding pseudo-rapidity distribution of hadron yields, and find decent agreement with experimental measurements in high-energy Pb+Pb, Au+Au, p+Pb, and d+Au collisions.
