论文摘要
我们回顾了3+1D Glasma模拟的进展，以描述重离子碰撞的最早阶段。在我们的模拟中，我们包括具有有限纵向范围的核，并描述了使用彩色粒子中的颜色粒子方法，在实验室框架中在实验室框架中强烈相互作用的gluonic场的演变。这使我们能够计算3+1维的Glasma Energy-Momentum Tensor，它们的速度依赖性可以与RHIC的实验性脉冲多重性数据进行比较。改进的方案可以治愈数值Cherenkov的不稳定性，并为LHC使用的较高能量的模拟铺平了道路。
We review our progress on 3+1D Glasma simulations to describe the earliest stages of heavy-ion collisions. In our simulations we include nuclei with finite longitudinal extent and describe the collision process as well as the evolution of the strongly interacting gluonic fields in the laboratory frame in 3+1 dimensions using the colored particle-in-cell method. This allows us to compute the 3+1 dimensional Glasma energy-momentum tensor, whose rapidity dependence can be compared to experimental pion multiplicity data from RHIC. An improved scheme cures the numerical Cherenkov instability and paves the way for simulations at higher energies used at LHC.
