Abstract

A simple method has been applied to solve the approximate gluon evolution equation for small-x at fixedρ(≡√ln(x 0/x)/ln[ln(Q 2/Λ2)/ln(Q 20 /Λ2)]. Numerical comparison is made with the predictions from ‘double asymptotic scaling’ and fit. Better agreement is found between our solution and fit nearρ=1. The solution gives approximate double scaling in this region having ‘hard’ pomeron with small contamination.
