Measurement of production and properties of jets at the CERN\(\bar pp\) collider

The production and properties of high transverse momentum hadron jets have been measured in the UA2 experiment at the CERN\(\bar pp\) Collider\((\sqrt s = 540 GEV)\) 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.
