Twist expansion of forward Drell-Yan process

Tomasz Stebel, Leszek Motyka, Mariusz Sadzikowski

摘要:

本文给出了高能前向Drell-Yan过程微分截面的扭曲展开式。在GBW饱和模型下展开了所有不变形状因子,饱和标度起着OPE强子标度的作用。给出了LHC实验的一些显式预言。它还示出了拉姆-董关系是如何被打破的扭曲4,这提供了一个灵敏的探针搜索更高的扭曲。

英文摘要:

We present a twist expansion of differential cross-sections of the forward Drell-Yan process at the high energies. The expansion of all invariant form-factors is performed assuming GBW saturation model and the saturation scale plays the role of the hadronic scale of OPE. Some expilicit predictions for LHC experiments are given. It is shown also how the Lam-Tung relation is broken at twist 4 what provides a sensitive probe for searching of higher twists.
