质子模型中夸克和胶子动量分数的分析

An Analysis of Momentum Fractions of Quarks and Gluons in a model of Proton

Akbari Jahan, D K Choudhury

摘要:

动量和定则可以作为一个不等式,在有限的\textit{x}范围内,估计质子模型中夸克和胶子动量分数的上、下界。我们计算这样的边界在一个自相似性为基础的模型,有效的质子结构功能的范围$ 6.2\times 10^{-7} \leq x \leq 10^{-2} $。结果符合渐近QCD期望。

英文摘要:

Momentum sum rule can be used as an inequality to estimate the lower and upper bounds of the momentum fractions of quarks and gluons in a model of proton valid in a limited \textit{x} range. We compute such bounds in a self-similarity based model of proton structure function valid in the range $ 6.2\times 10^{-7} \leq x \leq 10^{-2} $. The results conform to the asymptotic QCD expectations.
