论文摘要
由参数$σ= \ frac {1} {2} {2} b^-p^+$定义的Boost-Invariant纵向空间可以从分布的傅立叶变换上的共轭变量偏置$ξ$中研究。我们研究了穿着夸克模型的$σ$空间中的Quark Wigner分布，发现衍射模式类似于光学中的光实验。中央最大值的宽度随着能量转移到系统而变化，基本上$ξ$的行为就像狭缝宽度。最近在其他模型中报道了定性相似的衍射模式。在此模型中，我们计算所有针对夸克的非零偏度的领先扭转GTMD，这在傅立叶变换下提供了Wigner分布。
The boost-invariant longitudinal space, defined by the parameter $σ=\frac{1}{2}b^-P^+$ can be studied from the Fourier transformation of distributions over the conjugate variable skewness $ξ$. We investigate quark Wigner distributions in the $σ$ space in dressed quark model and found diffraction patterns that are analogous to the single slit experiment of light in optics. The width of the central maxima varies with energy transfer to the system and essentially $ξ$ behaves like a slit-width. Qualitatively similar diffraction pattern is reported recently in other models. In this model, we compute all the leading twist GTMDs with non-zero skewness for quarks which provides Wigner distributions under Fourier transformation.
