Book Description
We have studied the semi-inclusive reactions anti .nu.p .-->. .mu. V°X and .nu.p .-->. .mu.−V°X, and measured the fractional rate for producing one or more neutral strange particles in these reactions to be 0.16 +- 0.03 and 0.15 +- 0.04, respectively. We have observed K−(892) and .sigma.−(1385) production in anti .nu.p scattering at a few percent of the inclusive rate. No evidence for D° production was seen in the K/sub s/°.pi.pi.− final state. The distributions in the standard deep-inelastic kinematic variables are presented for events with strange particles and compared to those for the other charged current data. The fragmentation properties of events containing a K/sub s/° are in agreement with results from electroproduction experiments, and we have measured .integral.0 31 ° 1/N/sub T/ dn/dz dz/sub dz//sup dN/ dz = 0.029 +- 0.005, which is smaller than the prediction of the Field and Feynman fragmentation model.

Book Description
Neutral strange particle production in charged-current muon-neutrino interactions have been studied in the Fermilab 15-foot neon bubble chamber. Associated production is expected to be the major source of strange particles in charged-current neutrino interactions. sigma-neutral and xi-minus production by neutrinos was observed. The dependence on various leptonic and hadronic variables is investigated. A fit to single and associated production of s, s/anti-s, and c quarks is described based on the number of single and double strange particle production events. Inclusive neutral strange particle decays (V°) production rates as a fraction of all charged-current events are measured and are tabulated. The lambda/K ratio is found to be 0.39 +- 0.04 and the fraction of lambda coming from sigma-neutral is (16 +- 5)%. The single- and double V° production was used to determine the associated s anti-s production rate and single s-quark production rate. 13 refs., 7 figs., 3 tabs. (LEW).
