从胶子分布函数分析质子纵向结构函数

Analysis of the proton longitudinal structure function from the gluon distribution function

G. R. Boroun, B. Rezaei

摘要:

本文对Cooper- Sarkar等人(Z. Phys.C39:281,1988; Acta Phys.Pol.B34:2911 2003),其经常用于从小x处的质子纵向结构函数提取胶子分布。通过在特定的展开点处展开得到胶子密度,并与硬Pomeron行为的胶子密度进行了比较。与H1的数据进行比较,并预测所提出的最佳方法。

英文摘要:

We make a critical, next-to-leading order, study of the relationship between the longitudinal structure function FL and the gluon distribution proposed in Cooper- Sarkar et al. (Z. Phys. C 39:281, 1988; Acta Phys. Pol. B 34:2911 2003), which is frequently used to extract the gluon distribution from the proton longitudinal structure function at small x. The gluon density is obtained by expanding at particular choices of the point of expansion and compared with the hard Pomeron behavior for the gluon density. Comparisons with H1 data are made and predictions for the proposed best approach are also provided.
