Abstract
The inclusive forward jet cross section in deep inelastic e+p scattering
has been measured in the region of x-Bjorken,
to 
. This measurement is
motivated by the search for effects of BFKL-like parton shower evolution.
The cross section at hadron level as a function of x is compared to
cross sections predicted by various Monte Carlo models. An excess of
forward jet production at small x is observed, which is not reproduced by
models based on DGLAP parton shower evolution.
The Colour Dipole model describes the data reasonably well. Predictions
of perturbative QCD calculations at the parton level based on BFKL and DGLAP
parton evolution are discussed in the context of this measurement.
