Abstract

The results of a study of strange particle production in charged current νμN interactions in the Fermilab 15 ft bubble chamber filled with a heavy NeH2 mixture are presented. Production rates and average multiplicities of K0's and Λ's as functions of W2 and Q2 are given. The experimental data agree well with the quark-parton model predictions if a yield of 0.06 ± 0.02 of K0's and Λ's from charm production is included. Upper limits for D-meson production are given and the shape of the charmed quark fragmentation function is discussed. Inclusive production of the K(890) and Σ(1385) resonances is measured and it is shown that only about 5% of the K0 mesons and Λ hyperons results from resonance decays. Relative production rates of neutral strange particles on proton and neutron targets are studied.
