论文摘要
我们将Glasma的弱场近似延伸到增强不变近似之外，这使我们能够在重离子碰撞的早期阶段计算速度依赖性的可观察力。我们表明，在小磁场的极限中，弱场近似与非扰动晶格模拟定量一致。此外，我们证明了横向压力的速度曲线是由碰撞核内的纵向相关性确定的。
We extend the weak field approximation for the Glasma beyond the boost-invariant approximation, which allows us to compute rapidity-dependent observables in the early stages of heavy-ion collisions. We show that in the limit of small fields, the weak field approximation agrees quantitatively with non-perturbative lattice simulations. Furthermore, we demonstrate that the rapidity profile of the transverse pressure is determined by longitudinal color correlations within the colliding nuclei.
