The properties of high mass multijet events produced at the Fermilab proton-antiproton collider are compared with leading order QCD matrix element predictions, QCD parton shower Monte Carlo predictions, and the predictions from a model in which events are distributed uniformly over the available multibody phase-space. Multijet distributions corresponding to (4N-4) variables that span the N-body parameter space are found to be well described by the QCD calculations for inclusive three-, four-, and five-jet events. The agreement between data, QCD matrix element calculations, and QCD parton shower Monte Carlo predictions suggests that 2 --> 2 scattering plus gluon radiation provides a good first approximation to the full LO QCD matrix element for events with three, four, or even five jets.

The proceedings of this series of annual symposia represent an extensive summary of the experimental and theoretical status of high energy physics at hadron colliders. This volume discusses the latest results on top and beauty physics, QCD, electroweak physics and searches for new particles. The prospects of this field for LHC, Tevatron and Hera machines are also reported.

The proceedings presents in a systematic way Top searches, Jets, Gauge Boson production, precision tests of electroweak theory, Ln s Physics, heavy Flavours and exotics. In addition, contributions to the sessions 'News from the World', 'Short term future' and 'Long term future' show the progress of SSC in USA, of LHC at CERN, UNK/VLEPP in USSR together with Perspectives of Hadron Collider Physics.
