论文摘要
我们介绍了Parton模型中领先顺序Twist-3水平的带电当前的半包含的深度弹性散射过程的系统计算。我们考虑了带有旋转1的偏振靶标的负电荷梁的一般形式。计算是通过应用共线扩展来考虑多个Gluon散射并自动获得量规链路来进行的。我们首先通过运动学分析以结构函数呈现差分横截面的一般形式,然后根据规格不变的Parton分布函数呈现结构函数,最高为twist-3级别。考虑到横截面的角度调制和极化,我们计算了带电电流的半含量深度非弹性散射过程中的完全方位角不对称。在本文中还考虑了收费不对称的,并引入了$ plus $和$减去$ cross部分的定义。
We present a systematic calculation of the charged current semi-inclusive deeply inelastic scattering process at leading order twist-3 level in the parton model. We consider the general form of the negatively charged beam scattering off the polarized target which has spin-1. The calculations are carried out by applying the collinear expansion where multiple gluon scattering is taken into account and gauge links are obtained automatically. We first present the general form of the differential cross section in terms of the structure functions by kinematic analysis and then present the structure functions in terms of the the gauge invariant parton distribution functions up to twist-3 level. Considering the angle modulations and polarizations of the cross section, we calculate the complete azimuthal asymmetries in the charged current semi-inclusive deeply inelastic scattering process. The charge asymmetries are also considered in this paper with the introduction of the definitions of the $plus$ and $minus$ cross sections.
