GeV data for $k_{1\perp}, k_{2\perp} \geq 20 GeV$ gives $\alpha_P=1.35 \pm 0.04 (stat) \pm
0.22$ (syst) when (5.1) is used to fit the data. The strength of the DØanalysis is that $k_\perp > 20 GeV$ which makes uncertainties due to jet definition minimal. Weaknesses of the analysis are the large systematic error and the smallness of $\Delta Y,$ equal to 2, at the lower energy. We can hope that the systematic errors will come down in the near future.

Overall, I think the BFKL searches are encouraging but not yet definitive. The fact that all three analyses suggest a strong increase with energy of reliable quantities for isolating BFKL effects is certainly positive. An attempt will also be made to measure $\alpha_P-1$ at LEP\[44\] in the next year by measuring the $\gamma^*-\gamma^*$ total cross section. This is a very clean process, although the cross section is rather small.

Higher order corrections to BFKL evolution
==========================================

In general in QCD next-to-leading corrections are very important. It is only after next-to-leading corrections have been calculated that scales have a real meaning and normalizations can be trusted. In the case of BFKL evolution the next-to-leading corrections are also important to show that, in
