N2 - The forward-jet cross section in deep inelastic e+p scattering has been measured using the ZEUS detector at HERA with an integrated luminosity of 6.36 pb-1. The jet cross section is presented as a function of jet transverse energy squared, E(T,jet)/2, and Q2 in the kinematic ranges 10-2 < E(T,jet)/2/Q 2 < 102 and 2.5 · 10-4 < x < 8.0 · 10-2. Since the perturbative QCD predictions for this cross section are sensitive to the treatment of the log(E(T,jet)/2/Q2) terms, this measurement provides an important test. The measured cross section is compared to the predictions of a next-to-leading order pQCD calculation as well as to various leading-order Monte Carlo models. Whereas the predictions of all models agree with the measured cross section in the region of small E(T,jet/2/Q2 only one model, which includes a resolved photon component, describes the data over the whole kinematic range.
