Abstract: | A simple method has been applied to solve the approximate gluon evolution equation for small-x at fixedρ(≡√ln(x
0/x)/lnln(Q
2/Λ2)/ln(Q
0
2
/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. |
