在这一系列的三个讲座中，我们讨论了量子色动力学中强子间高能散射的几个方面。第一堂课介绍了部分子模型、Bjorken标度以及由于部分子分布随横向分辨率的演化而产生的标度破坏。第二讲描述了小动量分数x的部分子演化、胶子饱和现象和彩色玻璃凝聚体(CGC)。在第三讲中，我们介绍了CGC在高能强子碰撞研究中的应用，重点是核-核碰撞。特别地，我们给出了包含胶子产生的高能因式分解的证明。
In this series of three lectures, we discuss several aspects of high energy scattering among hadrons in Quantum Chromodynamics. The first lecture is devoted to a description of the parton model, Bjorken scaling and the scaling violations due to the evolution of parton distributions with the transverse resolution scale. The second lecture describes parton evolution at small momentum fraction x, the phenomenon of gluon saturation and the Color Glass Condensate (CGC). In the third lecture, we present the application of the CGC to the study of high energy hadronic collisions, with emphasis on nucleus-nucleus collisions. In particular, we provide the outline of a proof of high energy factorization for inclusive gluon production.
