摘要

本文介绍了用轻子束研究核子结构的最新物理学结果。讨论的主题是:i)夸克和胶子螺旋度测量的核子纵向自旋结构，ii)确定夸克碎片函数的强子多重性的半包容深度非弹性(SIDIS)结果，iii)通过SIDIS反应的横向动量依赖分布，iv)通过深度虚拟康普顿散射和介子产生的广义部分子分布研究。数据在JLab (6 GeV电子)、HERMES (27 GeV电子)和COMPASS (160/ 190 GeV介子)上采集。

Nucleon Structure Studies by Lepton Deep Inelastic Scattering

We present physics results obtained recently on the structure of the nucleon using lepton beams. The subjects discussed are: i) nucleon longitudinal spin structure with quark and gluon helicity measurements, ii) Semi-inclusive deep inelastic (SIDIS) results on hadron multiplicities for quark fragmentation function determination, iii) Transverse Momentum Dependent Distributions via SIDIS reactions and iv) Generalized Parton Distributions studies via Deep Virtual Compton Scattering and Meson Production. Data were taken at JLab (6 GeV electrons), HERMES (27 GeV electrons), and COMPASS (160/ 190 GeV muons).
