Forward and backward multiplicities inK − p interactions at 110 GeV/c

  • Published:

Abstract

Multiplicity distributions and correlations between charged particles in the forward and back-ward c.m. hemispheres are studied inK −p interactions at 110 GeV/c and compared with other data on mesonnucleon scattering. The interpretation in terms of a simple quark-parton picture assuming that the forward multiplicity is dominated by quark fragmentation and the backward multiplicity by diquark fragmentation is supported by the experimental fact that the forward and the backward mean multiplicities are approximately equal to half of thee + e − andpp multiplicities, respectively. The 110 GeV/cK −p data show significant correlations between the numbers of slow forward and slow backward particles, whereas the multiplicities of fast forward and fast backward particles are independent.
