关于极化DIS数据的QCD分析方法的几点注记
Some Remarks on Methods of QCD Analysis of Polarized DIS Data
摘要:
本文讨论了用不同的QCD方法对现有的极化DIS数据进行分析所得到的极化部分子密度的结果。证明了它们与分析中所用方法的依赖性,无论是否考虑了对自旋结构函数g_1的运动学和动力学1/Q^2修正。指出在前渐近区的精确数据要求QCD预测与该区域的数据更仔细地匹配,以便正确地确定极化PDF。
英文摘要:
The results on polarized parton densities (PDFs) obtained using different methods of QCD analysis of the present polarized DIS data are discussed. Their dependence on the method used in the analysis, accounting or not for the kinematic and dynamic 1/Q^2 corrections to spin structure function g_1, is demonstrated. It is pointed out that the precise data in the preasymptotic region require a more careful matching of the QCD predictions to the data in this region in order to determine the polarized PDFs correctly.
