[en] Multiplicity distributions of charged hadrons produced in νp interactions are studied using a sample of 7850 charged current interactions in BEBC. Multiplicity moments are studied as functions of the invariant mass of the hadronic system, W, and a comparison is made with other lepton- and hadron-induced reactions. The mean charged multiplicity < nsub(c)sub(h)> is found to increase linearly with 1nW². The other multiplicity moments indicate a close similarity between the neutrino scattering and the class of annihilation processes. A study of the multiplicity distributions in the forward and backward directions in the hadronic c.m.s. gives results in qualitative agreement with the quark parton model. (orig.)
