论文摘要
在QCD颜色偶极子方法中研究了RHIC和LHC能量的HADRONIC碰撞中的迅速产生。根据Parton饱和框架评估了$ PA $碰撞中核修饰因子的预测，并将结果与实验测量结果进行比较，这是不同速度箱在不同速度箱中光子横向动量的函数。模型的可靠性是通过Phenix，Atlas和Alice合作的数据执行的。此外，我们表明，观察到的$ x_t $ - 缩放$ pp $和$ pa $ collisisions的提示光子生产的尺度可以在QCD颜色偶极式形式主义中积极解决。
Prompt photon production in hadronic collisions at the RHIC and the LHC energies is investigated within the QCD color dipole approach. Predictions for the nuclear modification factor in $pA$ collisions are evaluated based on parton saturation framework and the results are compared to the experimental measurements as a function of the photon transverse momentum at different rapidity bins. The reliability of the models is performed with the data from PHENIX, ATLAS, and ALICE Collaborations. Moreover, we show that the observed $x_T$-scaling of prompt photon production in $pp$ and $pA$ collisions can positively be addressed in the QCD color dipole formalism.
