极化部分子的自旋分布与相关的质子结构函数

THE SPIN DISTRIBUTION OF THE POLARIZED PARTON AND THE PROTON'S STRUCTURE FUNCTION OF THE DEPENDENT SPIN

讨论了极化质子内部分子自旋对质子自旋的贡献,与自旋相关的质子结构函数（?）的一次矩及xg1p的函数分布。由于极化质子内的部分子与非极化的质子内部分子分布关联,构造了关联函数把它们联系了起来。同时把胶子的反常贡献和轨道角动量的贡献都考虑在内,计算结果与实验数据符合很好。

The spin of the partons in the polarized proton contribution to the proton spin,the first moment of the proton's structure function of the dependent spin and distribution of the xgp1 are discussed. Suppose the distribution function of the parton in the polarized parton is connected with that of the unpolarized parton,and connection functions are constructed. A better agreement with the experimental data is obtained when it accounted for the contributions of anomalous gluons and orbital angle momentum.
