Abstract

The Generalized Parton Distributions (GPDs) correlate the transverse spatial distribution of the partons to their longitudinal momentum inside the nucleon and give a three-dimensional description of the nucleon. At COMPASS, GPDs are investigated via exclusive processes including Deeply Virtual Compton Scattering (DVCS) and Hard Exclusive Meson Production (HEMP) in the Bjorken variable coverage of the sea-quark domain. The exclusive measurements at COMPASS are discussed and some of the recent progresses are given in this article

广义部子分布(GPDs)将部子的横向空间分布与其在核子内的纵向动量联系起来，给出了核子的三维描述。COMPASS通过深度虚拟康普顿散射(deep Virtual Compton Scattering, DVCS)和硬独占介子产生(Hard exclusive Meson Production, HEMP)等独占过程在海夸克域的Bjorken可变覆盖范围内研究了gpd。本文讨论了COMPASS的独家测量，并给出了一些最新进展
