对类时和类空DVCS的NLO修正

NLO corrections to timelike and spacelike DVCS

B. Pire, L. Szymanowski, J. Wagner

摘要:

广义部分子分布(GPD)为研究夸克和胶子的核子结构提供了一种新的途径。我们主张,需要补充的实验研究的深度虚拟康普顿散射的交叉版本,类时康普顿散射。我们回顾了这一领域的最新进展,强调需要包括非线性光学校正的任何唯象程序提取GPD的实验数据。

英文摘要:

Generalized Parton Distributions (GPDs) offer a new way to access the quark and gluon nucleon structure. We advocate the need to supplement the experimental study of deeply virtual Compton scattering by its crossed version, timelike Compton scattering. We review recent progress in this domain, emphasizing the need to include NLO corrections to any phenomenological program to extract GPDs from experimental data.
