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

Abstract

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 $6.2\times 10^{-7}\le x\le 10^{-2}$. The results conform to the asymptotic QCD expectations.
