论运行耦合常数在奇T模的夸克模型分析中的作用

On the Role of the Running Coupling Constant in a Quark Model Analysis of T-odd TMDs

A. Courtoy

摘要:

我们重新审视的标准程序,以匹配非微扰模型微扰QCD,使用实验数据。强耦合常数在部分子密度的QCD演化中起着中心作用。我们将扩展这一过程的QCD运行耦合的非微扰推广,并使用这一新的发展,以了解为什么微扰治疗的强子模型的上下文中工作得相当不错。反之亦然,这个新的程序拓宽了分析冻结的运行耦合常数的方法。

英文摘要:

We revisit the standard procedure to match non-perturbative models to perturbative QCD, using experimental data. The strong coupling constant plays a central role in the QCD evolution of parton densities. We will extend this procedure with a non-perturbative generalization of the QCD running coupling and use this new development to understand why perturbative treatments are working reasonably well in the context of hadronic models. Vice versa, this new procedure broadens the ways of analyzing the freezing of the running coupling constant.
