Abstract

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 Q(2) in the kinematic ranges 10(-2) lt E-T,jet(2)/Q(2) lt 10(2) and 2.5.10(-4) lt x lt 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)/Q(2)) 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)/Q(2), only one model, which includes a resolved photon component, describes the data over the whole kinematic range.
