Abstract Using data onvp and $$\bar vp$$ charged current interactions from a bubble chamber experiment with BEBC at CERN, the average multiplicities of charged hadrons and pions are determined as functions ofW 2 andQ 2. The analysis is based on ∼20000 events with incidentv and ∼10000 events with incident $$\bar v$$ . In addition to the known dependence of the average multiplicity onW 2 a weak dependence onQ 2 for fixed intervals ofW is observed. ForW〉2 GeV andQ 2〉0.1 GeV2 the average multiplicity of charged hadrons is well described by〈n〉=a 1+a 2ln(W 2/GeV2)+a 3ln(Q 2/GeV2) witha 1=0.465±0.053,a 2=1.211±0.021,a 3=0.103±0.014 for thevp anda 1=−0.372±0.073,a 2=1.245±0.028,a 3=0.093±0.015 for the $$\bar vp$$ reaction.
