光锥夸克模型中核子的自旋结构

The spin structure of the nucleon in light-cone quark models

B. Pasquini, S. Boffi, P. Schweitzer

摘要:

在光锥夸克模型中,讨论了夸克自旋密度与碰撞参数空间中广义部分子分布和与横动量相关的部分子分布的关系,重点讨论了夸克自旋-自旋和自旋-轨道相关的作用,并讨论了由T偶横动量相关的部分子分布引起的半包容深度非弹性散射中的方位角自旋不对称性.

英文摘要:

The quark spin densities related to generalized parton distributions in impact-parameter space and to transverse-momentum dependent parton distributions are reviewed within a light-cone quark model, with focus on the role of the different spin-spin and spin-orbit correlations of quarks.Results for azimuthal spin asymmetries in semi-inclusive deep-inelastic scattering due to T-even transverse-momentum dependent parton distributions are also discussed.
