摘要：
Multi-hadron production in inelastic neutrino-nucleon interactions is investigated within the framework of the quark-gluon string model. The contributions of the planar (one-reggeon exchange) and cylindrical (one-pomeron exchange) graphs to different observables is computed using a Monte Carlo program for the generation of hadrons produced from the decay of colorless quark-antiquark strings. The suggested approach results in a satisfactory description of the experimental data on nu(nu)N --> mu(-)(mu(+))hX reactions obtained recently at CERN by the NOMAD Collaboration. The data extends over a wide range of initial neutrino energies E-nu < 200 GeV/c and momentum transfers 1 < Q < 7 GeV/c, well into the region where perturbative QCD calculations are not applicable.
