Charged current events with neutral strange particles in high energy antineutrino interactions

Strange particle production in charged current anti(MU)sub((SIGMA))N interactions in the Fermilab 15-Ft. bubble chamber filled with a heavy Ne-H2 mixture was studied. Production rates and average multiplicities of K0's and lambda's as functions of W(2) and Q(2) W(2) is the total hadronic invariant mass and Q(2) is the square of the four momentum transfer) are given. The experimental data agree well with the quark-parton model predictions if a relative yield of 0.06+-0.02 of K0's and lambda's from the charm production is included. Upper limits for the D-meson production are given and shape of the charmed quark fragmentation function is discussed. Inclusive production of the K*(890) and (UC OMEGA)(1385) resonances is considered. Relative production rates of neutral strange particles on proton and neutron targets were also studied.
