| Abstract | A large solid-angle apparatus consisting of a superconducting solenoid magnet, cylindrical drift chambers and two arrays of lead-glass counters was used to examine particles associated with a high transverse momentum trigger in p-p collisions with three square root s values at the CERN ISR. The trigger was given by energy deposition in lead-glass arrays centered at 90 degrees . The trigger transverse momentum range covered was 3<p/sub Ttrig/ <11 GeV/c. Results are given for p/sub out/ for both individual charged particles, and also for the sum of charged particle momenta in the hemisphere opposite to the trigger. Mean values are then deduced for the parton transverse momentum k/sub T/, and for the jet fragmentation momentum j/sub T/. Results of a jet analysis are also presented. (14 refs). |
