Inclusive neutral-strange-particle production from high-energyνpcharged-current interactions

We have studied the properties of inclusive neutral-strange-particle production in charged-current ..nu..p interactions. The rate for producing at least one neutral strange particle in a charged-current interaction is 0.14 +- 0.02. The inclusive distributions for events with neutral strange particles and for all charged-current events exhibit the same qaulitative behavior. We find no acceptable candidates for the ..delta..S = - ..delta..Q ..lambda.. production reaction ..nu..p ..-->.. ..mu../sup -/2..pi../sup +/..pi../sup -/ in approximately 3000 charged-current events with E/sub ..nu../ > 10 GeV. We find upper limits (relative to the total charged-current sample) for charmed-particle production in any one mass region with subsequent decay into ..lambda..m..pi.. and Km..pi.. final states of 1% and 2%, respectively.
