Inclusive F2 (1270) Meson Production In Nu-P And Nu-Barp Charged Current Interactions

Using data obtained with the bubble chamber BEBC at CERN, the inclusive f2(1270) meson production in nu-p and nu-BARp charged current reactions is studied. It is found that f2 production occurs mainly in events with a hadronic invariant mass W greater-than-or-similar-to 7 GeV. In these events, the average f2 multiplicity is about half the average rho-0 multiplicity, and the x(F) and p(T)2 distributions of the f2 agree in shape with those of the rho-0. The predictions of a Semi-empirical model (Wells model) are in accord with the measured multiplicities at W > 7 GeV, whereas at lower W the model predicts too large f2 multiplicities.
