B. Pasquini, S. Boffi, A. V. Efremov, P. Schweitzer

摘要:

本文综述了核子的光锥组分夸克模型中主导扭转横动量相关部分子分布的主要性质,着重讨论了夸克的自旋-自旋关联和自旋-轨道关联的作用。还讨论了半包容深非弹性散射中方位角单自旋不对称性的结果。

英文摘要:

The main properties of the leading-twist transverse momentum dependent parton distributions in a light-cone constituent quark model of the nucleon are reviewed, with focus on the role of the spin-spin and spin-orbit correlations of quarks. Results for azimuthal single spin asymmetries in semi-inclusive deep inelastic scattering are also discussed.
