Inclusive ρ 0 production in neutrino-proton charged-current interactions is studied, using a sample of 7831 events obtained in BEBC filled with hydrogen and exposed to the CERN wideband neutrino beam. An average multiplicity of 0.14±0.02 ρ 0 per event is found, corresponding to a ratio 〈 ρ 0 〉/〈 π − 〉=0.13±0.02. The ρ 0 production characteristics are determined as functions of leptonic variables ( W , Q 2 , χ B ) and hadronic variables ( χ F , z , p t 2 ) and are found to be similar to those determined for hadron- and other lepton-induced reactions.
