Abstract

We present stdies of events triggered on two high-p_T jets, produced in pp collisions at the CERN Intersecting Storage Rings (ISR) at {Mathematical expression}=63 GeV, using a large solid angle calorimeter. The cross-section for producing two jets is measured in the dijet mass range 17-50 GeV/c². A high-statistics sample of dijet events, where each jet has transverse energy above 10 GeV, is used to study the structure of jets and the associated event. We find the longitudinal fragmentation function to be similar to that of jets emerging from e⁺e^- collisions but considerably harder than that observed at the Super Proton Synchrotron (SPS) {Mathematical expression} Collider. A steepening of the fragmentation function is observed when increasing the jet energy. Studies of the charge distribution in jets show that these predominantly originate from fragmenting valence quarks. The transverse energy and particle flows are presented as functions of the azimuthal distance from the jet axis.
