four as $x$ goes from about $3x10^{-3}$ to about $7x10^{-4}$ for $k_{1\perp} > 3.5 GeV.$ This is a growth quite a bit faster than given in conventional Monte Carlos and much faster than the growth from single gluon exchange between the measured jet and the quark-antiquark pair coming from the virtual photon. The growth is comparable to that given in (5.2), for $\alpha_P-1 \approx 1/2,$ however, the comparison is not completely convincing because a comparison of partonic energy dependences, from (5.2), with hadron final states is not very reliable when $k_{1\perp}$ is as small as in the $H1$ analyses.

Recently ZEUS\[13\] has completed an analysis of this process. Since the ARIADNE Monte Carlo gives a good fit to the ZEUS data this Monte Carlo is used to unfold the hadronization and thus get a better comparison with BFKL evolution. The data agree much better with BFKL evolution than with the Born term or with next-to-leading order QCD calculations. A definitive comparison with BFKL dynamics is hindered by the lack of ability to include hadronization corrections along with the BFKL evolution. One can hope that the situation will soon improve in this regard.
