高能质子-核碰撞中的第一饱和修正:II。单包容半硬胶子的产生

First Saturation Correction in High Energy Proton-Nucleus Collisions: II. Single Inclusive Semi-Hard Gluon Production

Ming Li, Vladimir V. Skokov

摘要:

利用最近得到的经典Yang-Mills方程在稀体(质子)场中的高阶微扰解析解,利用Lehmann-Symanzik-Zimmermann约化公式,导出了高能质子-核碰撞中单个包含半硬胶子产生的完全第一饱和修正.这样,我们就完成了Balitsky开始的程序(见参考文献~)。\cite{Balitsky:2004rr})以及Chirilli、Kovchegov和Wertepny独立提出的(参见参考文献~ \cite{Chirilli:2015tea}),尽管使用了非常不同的方法来执行我们的计算。我们提取了胶子谱对碰撞物体色荷密度的函数依赖性,从而我们的结果可以用来评估对双/多重包含胶子产生的完全第一饱和修正.

英文摘要:

Exploiting recently obtained analytic solutions of classical Yang-Mills equations for higher order perturbations in the field of the dilute object (proton), we derive the complete first saturation correction to the single inclusive semi-hard gluon production in high energy proton-nucleus collisions by applying the Lehmann-Symanzik-Zimmermann reduction formula. We thus finalize the program started by Balitsky (see Ref.~\cite{Balitsky:2004rr}) and independently by Chirilli, Kovchegov and Wertepny (see Ref.~\cite{Chirilli:2015tea}) albeit using a very different approach to carry out our calculations. We extracted the functional dependence of gluon spectrum on the color charge densities of the colliding objects; thus our results can be used to evaluate complete first saturation correction to the double/multiple inclusive gluon productions.
