| Abstract |
New parton dynamics, characterised by an initial state cascade, which is
non-ordered in parton virtuality, is expected to become important in the
kinematical region of small Bjorken-x. Evidence for this is searched for
by studying events with a forward jet produced close to the direction of
the incoming proton in the angular region 7^o < theta < 20^o. The
cross-section is presented as a function of x. The energy flow around the
forward jet has also been measured to investigate how the energy
compensation is described by models and if the forward jet changes with
rapidity. The triple differential cross-section d3sigma/dxdQ2dpt2 is
presented in the phase regions associated with direct photon, BFKL and
resolved photon effects. In addition events containing a hard dijet system
in addition to the forward jets has also been measured. The data are
compared with the predictions of various QCD-based models. |
