论文摘要
我们提出了一个最先进的计算，用于在LHC的质子 - 蛋白质和质子铅碰撞中生产前向二颗，在速度范围内被ATLAS量热计覆盖，并计划在爱丽丝检测器的焦点扩展。我们使用Small-X改进的TMD（ITMD）形式主义，以及共线改进的TMD Gluon分布和完整的B空间Sudakov重新召集，并讨论了由于强调和使用Pythia事件生成器而引起的非扰动校正。我们观察到，质子核核碰撞中的前向二颗PT中的前向二行是饱和效应的出色探针，因为Sudakov的重新召集不会改变对横截面的抑制。
We present a state-of-the-art computation for the production of forward dijets in proton-proton and proton-lead collisions at the LHC, in rapidity domains covered by the ATLAS calorimeter and the planned FoCal extension of the ALICE detector. We use the small-x improved TMD (ITMD) formalism, together with collinearly improved TMD gluon distributions and full b-space Sudakov resummation, and discuss nonperturbative corrections due to hadronization and showers using the Pythia event generator. We observe that forward dijets in proton-nucleus collisions at moderately low pT are excellent probes of saturation effects, as the Sudakov resummation does not alter the suppression of the cross section.
