Inclusive f2 (1270) meson production in ν p and $$\bar v p$$ charged current interactions

Using data obtained with the bubble chamber BEBC at CERN, the inclusivef2 (1270) meson production invp and\(\bar vp\) charged current reactions is studied. It is found thatf2 production occurs mainly in events with a hadronic invariant massW≳7 GeV. In these events, the averagef2 multiplicity is about half the average ρO multiplicity, and thex F andp T 2 distributions of thef2 agree in shape with those of the ρO. The predictions of a semi-empirical model (Wells model) are in accord with the measured multiplicities atW>7 GeV, whereas at lowerW the model predicts too largef2 multiplicities.
