Abstract
- Inclusive ϱ0 production has been studied in antineutrino-proton charged current interactions, using a sample of 3340 events obtained in BEBC filled with hydrogen and exposed to the CERN wideband antineutrino beam. An average multiplicity of 0.11 ± 0.02ϱ0 per event at a mean hadronic mass W of 4.2 GeV is observed. The ϱ0 production characteristics are determined as functions of pT, xF, and z. The ratio ϱ0/“π0” is found to be low at small z values consistent with centrally produced pions coming mainly from resonances. At large z values this ratio approaches 0.45 ± 0.15 which is compatible with a vector/pseudoscalar meson direct production ratio of one. The results are compared with those obtained from neutrino-proton interactions in the same experimental set-up.
