光锥上核子自旋的结构

Structure of the Nucleon Spin on the Light Cone

B. Pasquini

摘要:

本文在核子的光锥描述中研究核子的自旋结构,其中Fock展开被截断为只考虑价夸克。通过碰撞参数空间中的广义部分子分布定义了与横动量相关的部分子分布和横自旋密度,作为揭示不同夸克和核子极化下自旋-自旋和自旋-轨道关联的新工具.

英文摘要:

The spin structure of the nucleon is studied in a light-cone description of the nucleon where the Fock expansion is truncated to consider only valence quarks. Transverse momentum dependent parton distributions and transverse-spin densities, defined through the generalized parton distributions in the impact-parameter space, are investigated as new tools to reveal the spin-spin and spin-orbit correlations for different quark and nucleon polarizations.
