深虚Compton散射中的软共线重算

Soft-collinear resummation in deeply virtual Compton scattering

T. Altinoluk, B. Pire, L. Szymanowski, S. Wallon

摘要:

在非单重态夸克系数函数中考虑了软胶子交换的影响,导出了深虚康普顿散射(DVCS)振幅的全阶重算公式。我们确定了类光规范中[α S log^2(x +/- xi)]^n贡献的梯形图。该序列的结果是一个简单的封闭表达式。

英文摘要:

We derive an all order resummation formula for the deeply virtual Compton scattering (DVCS) amplitude, which takes into account soft gluon exchanges in the non-singlet quark coefficient function. We identify the ladder diagrams responsible in light-like gauge for [alphaS log^2 (x +/- xi)]^n contributions. The resummed series results in a simple closed expression.
