核上硬过程的么正切割规则

Unitarity cutting rules for hard processes on nuclei

W. Schäfer

摘要:

重核在pQCD中引入了一个新的标度--饱和标度,打破了人们熟悉的线性k_ \perp -因子分解。用非线性k_ \perp -因子分解的概念来代替。本文简要介绍了如何用非线性k_ \perp -因子分解方法得到核上硬过程的拓扑截面。

英文摘要:

Heavy nuclei introduce a new scale into the pQCD description of hard processes on nuclei, the saturation scale, and the familiar linear k_\perp-factorization breaks down. It is replaced by a new concept, the nonlinear k_\perp-factorization. Here we give a brief overview how topological cross sections for hard processes on nuclei are obtained from nonlinear k_\perp-factorization.
