Description
Using data on νp and anti νp charged current interactions from a bubble chamber experiment with BEBC at CERN, the average multiplicities of charged hadrons and pions are determined as functions of W2 and Q2. The analysis is based on ∝20000 events with incident ν and ∝10000 events with incident anti ν. In addition to the known dependence of the average multiplicity on W2 a weak dependence on Q2 for fixed intervals of W is observed. For W>2 Gev and Q2>0.1 GeV2 the average multiplicity of charged hadrons is well described by =a1+a2 ln(W2/GeV2)+a3ln(Q2/GeV2) with a1=0.465±0.053, a2=1.211±0.021, a3=0.103±0.014 for the νp and a1=-0.372±0.073, a2=1.245±0.028, a=30.093±0.015 for the anti νp reaction.
