小$x$质子结构函数模型中夸克和胶子携带的动量分数

Momentum Fractions carried by quarks and gluons in models of proton structure functions at small $x$

D K Choudhury, Baishali Saikia, K Kalita

摘要:

本文报道了在小$x$上对质子结构函数模型中夸克和胶子所携带的动量分数的分析。首先,我们分析了Lastovicka提出的基于自相似性的模型。然后,我们基于同样的概念对第二个模型进行类似的分析,该模型也没有$x$中的奇异性:$0<x<1$。这两个模型的预测,然后与最近的QCD为基础的Froissart绑定兼容模型的质子结构功能在小$x$,建议块,杜兰德,哈和麦凯。并将所得结果与微扰和格点量子色动力学的相应结果进行了比较。

英文摘要:

The paper reports analysis of momentum fractions carried by quarks and gluons in models of Proton structure functions at small $x$. First, we analyze the model proposed by Lastovicka based on self-similarity sometime back. We then make a similar analysis for a second model based on the same notion which is also free from singularity in $x$ : $0<x<1$. The predictions of both the models are then compared with a recent QCD based Froissart bound compatible model of proton structure function at small $x$, suggested by Block, Durand, Ha and McKay. The results are then compared with the corresponding study in perturbative and Lattice QCD.
