Non-singlet structure function F_2~(NS) (x, t) in DGLAP approach

摘要

In this work the non-singlet structure function F_2~(NS) (x, t) have been obtained by solving DGLAP evolution equation in leading order (LO) at the small x limit. Here we have used a Taylor series expansion and then the method of characteristics and Lagrange's method to solve the evolution equations. We make a detailed comparison of the predictions of the two methods with two difierent levels of approximations with experimental data as well as with numerical solutions.
