Abstract

We present the gluon generalized TMDs for non-zero skewness and Wigner distributions in the boost invariant longitudinal space. The boost-invariant longitudinal space is defined as σ=12bΔ+ and is conjugate to the skewness variable ξ. We use the dressed quark model, where a high-energetic quark is dressed by a gluon. This two-particle system has the advantage of addressing both the gluon and the quark sectors. The different contributions in Wigner distributions coming from different polarization of gluon and the dressed quark system are investigated.

提升不变纵向空间中的胶子广义 TMD 和 Wigner 分布
我们提出了在助推不变纵向空间中的非零偏度和维格纳分布的胶子广义 TMD。助推不变纵向空间定义为 σ=12b-Δ+,并与偏度变量ξ共轭。我们使用穿载夸克模型,即高能夸克被胶子穿载。这种双粒子系统的优点是可以同时处理胶子和夸克部门。我们研究了不同极化的胶子和包被夸克系统对维格纳分布的不同贡献。
