矢量介子电产生的普适性

Universality in the Electroproduction of Vector Mesons

V. L. Baltar, H. G. Dosch, E. Ferreira

摘要:

我们研究普遍性的矢量介子的电生产使用统一的非微扰方法,已被证明是非常好的再现现有的实验数据。在这个框架中,在提取每个矢量介子特有的因子之后,我们得到了一个通用的简化的积分弹性截面。我们的计算表明,有限的红外行为的强耦合常数。

英文摘要:

We study universality in the electroproduction of vector mesons using a unified nonperturbative approach which has already proved to reproduce extremely well the available experimental data. In this framework, after the extraction of factors that are specific of each vector meson, we arrive at a reduced integrated elastic cross section which is universal. Our calculations suggest a finite infrared behavior for the strong coupling constant.
