Jets and correlations in large p/sub T/ reactions

Recent experimental data on correlations in large transverse momentum reactions are analyzed in a two-jet picture. Scaling in jet fragmentation is shown to account well for the existing data. The formulae that are given can be used as a basis for a more detailed analysis of the dynamics. A particular result is that a two-jet structure can also be produced in events where it is not required that any single hadron has large p/sub T/, with a cross section as large as /sup 1///sub 10/ mb or more (at ISR energies with the total transverse momentum of each jet >or=2.5 GeV/c).
