Quantum number effects in events with a charged particle at large transverse momentum (charge correlations in jets)

Charge correlations of particles in an event with a large p/sub t/ trigger particle have been measured. The correlation length for the charge compensation of the hard scattered parton fragments is the same as observed in nondiffractive inelastic events. Part of the charge of the large p/sub t/ trigger particle is compensated by the soft particles of the 'away jet'. For the spectator fragments the same charge correlation distributions are observed as for nondiffractive inelastic events. (8 refs).
