论文摘要
我们挑出了完全相干诱导的Gluon辐射在PA碰撞中产生的轻型强子的作用。该效果具有有趣的颜色结构，因为诱导的辐射取决于党派子过程最终状态的全局颜色电荷。仅考虑到完全相干能量损失的效果，提供了LHC处PPB碰撞中轻核抑制的基线预测，这证明了与Gluon阴影或饱和度相同的数量级。这强调了需要在PA碰撞中的强子产生的现象学研究中包括完全相干的能量损失。
We single out the role of fully coherent induced gluon radiation on light hadron production in pA collisions. The effect has an interesting color structure, as the induced radiation depends on the global color charge of the partonic subprocess final state. Baseline predictions for light hadron nuclear suppression in pPb collisions at the LHC are provided, taking into account only the effect of fully coherent energy loss, which proves of the same order of magnitude as gluon shadowing or saturation. This underlines the need to include fully coherent energy loss in phenomenological studies of hadron production in pA collisions.
