Quark Jet Model Study of Forward and Backward Multiplicities in νp and \barνp Interactions

Abstract

Based on the quark jet model we calculate the forward and backward multiplicities in νp and \barνp interactions. In these calculations the observed rapidity distributions of particles produced in e⁺e⁻ annihilations are used as input data to determine the rapidity distribution of secondary particles in the quark jet. The model describes the ν(\barν)p forward and backward multiplicities successfully, if we choose the inelasticity parameter η to be 0.46. This result suggests that the inelasticity parameter takes different values for leptonic and hadronic interactions.
