矢量介子光生和电生的非微扰和微扰性质

Nonperturbative and perturbative aspects of photo- and electroproduction of vector mesons

H. G. Dosch, Erasmo Ferreira

摘要:

我们讨论矢量介子生产的各个方面,首先分析微扰和非微扰方面的QCD计算之间的相互作用。使用一个通用的方法,适用于将微扰和非微扰方面,我们表明,非微扰效应是重要的所有实验可用的值的光子虚Q2。我们比较了大量的实验信息,现在我们的理论结果,使用一个特定的非微扰模型没有自由参数,表明相当简单的功能是能够解释的数据。

英文摘要:

We discuss various aspects of vector meson production, first analysing the interplay between perturbative and nonperturbative aspects of the QCD calculation. Using a general method adapted to incorporate both perturbative and nonpertubative aspects, we show that nonperturbative effects are important for all experimentally available values of the photon virtuality Q2. We compare the huge amount of experimental information now available with our theoretical results obtained using a specific nonperturbative model without free parameters, showing that quite simple features are able to explain the data.
