method allowing for a direct comparison of data with theoretical prediction
s is proposed for forward jet production at DESY HERA. It avoids the recons
truction of multiparton contributions by expressing the experimental cuts d
irectly as correction factors on the QCD forward jet cross section. An appl
ication to the determination of the effective Pomeron intercept in the Bali
tskii-Fadin-Kuraev-Lipatov (BFKL)-leading-order (LO) parametrization from d
sigma/dx data at HERA leads to a good fit with a significantly higher effe
ctive intercept, alpha(P) = 1.43 +/- 0.025(stat) +/- 0.025(syst), than for
proton (total and diffractive) structure functions. Tt is, however, less th
an the value of the Pomeron intercept using dijets with large rapidity inte
rvals obtained at the Fermilab Tevatron. We also evaluate the rapidity veto
contribution to the higher-order BFKL corrections. The method can he exten
ded to other theoretical inputs.
