Based on the spin-dependent quark distribution,the spin-dependent proton structure function in the large x region is presented in the paper.
从自旋相关的价夸克分布出发,在部分子四动量较大的区域(大x区域),给出了自旋相关的质子结构函数,并将其理论结果与Capella模型给出的结构函数及NMC实验结果进行了比较,其理论结果与实验符合较好。
Taking into account SU(6) symmetrical broken and the correction from PQCD predictions,the paper,with the aid of the quark-diquark picture,from Cappela s proton structure model,extracts a spin-correlation quark distribution with more explicit physical significance.
本文采用质子的夸克-双夸克模型图像,考虑到SU(6)对称性破缺及来自PQCD语言的修正,从Cappela的质子结构模型中提取出了具有更为明确物理意义的自旋相关的夸克分布。
