using a highly segmented total absorption calorimeter. The characteristics of a sample of two-jet events with invariant mass up to 200 GeV/c2 are discussed, including measurements of their fragmentation properties, angular and rapidity distributions, and the properties of the additional energy clusters accompanying the two-jet system. Cross sections for inclusive jet production in the jet transverse momentum range between 30 and 100 GeV/c and for the two-jet invariant mass distribution in the mass range from 60–200 GeV/c2 are reported.

collider using the UA2 detector in various ranges of transverse momentum (PT ) and pseudo-rapidity (η). Cross-section measurements are presented forπ0 production (PT ≦15 GeV/c, |η|≦0.85 andPT ≦40 GeV/c, 1.0≦|η|≦1.8), for η meson production (3≦PT ≦6 GeV/c, |η|≦0.85) and for charged particle production (PT ≦10 GeV/c, 1.0≦|η|≦1.8). Results are compared with the predictions of QCD calculations.

=540 GeV). From a sample of events containing an electron candidate withpT >15 GeV/c, we extract a clear signal resulting from the production of the charged intermediate vector bosonW± , which subsequently decays into an electron and a neutrino. We study theW production and decay properties. Further-more, we refine our results on the production and decay of the neutral vector bosonZ0 . Finally, we compare the experimental results to the predictions of the standard model of the unified electro-weak theory.
