从魅力结构函数$F^{c}_{2}$导出纵向结构函数$F_{L}$

Longitudinal Structure Function $F_{L}$ from Charm Structure Function $F^{c}_{2}$

B. Rezaei, G. R. Boroun

摘要:

我们预测了在小x时魅力结构函数对纵向结构函数的影响。在非线性光学分析中,我们发现在小的x值下,硬Pomeron行为对$F_{L}$和$F^{c}_{k}$(k = 2,L)给出了很好的描述.我们的结论是,$F_{L}/F^{c}_{2}$之间的直接关系将提供有用的信息,如何测量纵向结构功能在高$Q^{2}$值。经过检查,该模型与其他模型相比,对数据进行了良好的描述。

英文摘要:

We predict the effect of the charm structure function on the longitudinal structure function at small x. In NLO analysis we find that the hard Pomeron behavior gives a good description of $F_{L}$ and $F^{c}_{k}$ (k = 2,L) at small x values. We conclude that a direct relation between $F_{L}/F^{c}_{2}$ would provide useful information on how to measure longitudinal structure function at high $Q^{2}$ values. Having checked that this model gives a good description of the data, when compared with other models.
