| Abstract: | We found an approximate simple solution of sea-quark evolution equation in terms ofρ(=√ln(x 0/x)/ln[ln(Q 2/Λ2)/(Q 0 2 /Λ2)]) andζ(≡ln[ln(Q 2Λ2)/ln(Q 0 2 /Λ2)]) in the small-x region whenρ is fixed and compared with HERA data. Agreement with data is found for largeQ 2 and smallρ. Comparison with double asymptotic scaling prediction is made. We found a critical value ofρ. More data are needed to confirm this point. |
