Inclusive production of nonstrange resonances in high-energy νp charged-current interactions

We have examined the inclusive production of nonstrange particle resonances in ..nu..p interactions using the Fermilab 15-ft bubble chamber. A sample of 2437 charged-current events with visible longitudinal momentum greater than 10 GeV/c was obtained. The rho/sup 0/ and ..delta../sup + +/(1232) are seen. An overall rate of 0.21 +- 0.04 rho/sup 0/ per event is found. For five-prong events, the rate is 0.44 +- 0.08 rho/sup 0/ per event. The rho/sup 0/ Z distribution falls rapidly for Z greater than 0.4. The production of ..delta../sup + +/ is seen clearly in events with an identified proton. No evidence is seen for ..delta../sup 0/ production. An upper limit of 0.34 is placed on the ratio of eta/..pi../sup 0/ (90% confidence level).
