CGC下一到-eikonal准确性下前向夸克-核散射

我们推导了从穿越强脉冲势阱背景场前到后的夸克传播子在下一到-eikonal(NEik)精度下的完整修正，包括超越脉冲极限和超越静态极限的修正。After summarizing the full NEik corrections to the before-to-after quark propagator computed in our earlier works, we also derive the before-to-inside, inside-to-inside and inside-to-after quark and gluon propagators, which are building blocks to calculate high-energy scattering processes at NEik order. Using these results and also including the NEik corrections that stem from interactions with the target via t-channel quark exchanges, we compute inclusive cross sections for quark and gluon production at forward rapidities in quark-nucleus and gluon-nucleus scatterings at NEik accuracy.
