光子GPD的解析性和求和规则

Analyticity and sum rules for photon GPDs

I. R. Gabdrakhmanov, O. V. Teryaev

摘要:

以光子为研究对象,考察了QCD在微扰可计算共线部分子分布中的应用。我们研究的DVCS振幅的分析性质和相关的广义部分子分布的光子的求和规则作为输入,他们以前的计算在领导秩序。这些GPD的典型功能的双重参数化方法的框架中的关系也被发现。

英文摘要:

The photon is explored as an object to test the applications of QCD to the perturbatively calculable collinear parton distributions. We investigate analytic properties of DVCS amplitudes and related sum rules of generalized parton distributions of the photon using as an input their earlier calculations in the leading order. The relation of these GPDs to the quintessential functions in the framework of the dual parametrization approach is also found.
