Received 23 August 1996; published in the issue dated 25 November 1996
We use data collected by the CLEO II detector at the Cornell Electron Storage Ring (CESR) to search for B+→h+h-h+ (nonresonant) decays, where h± can be either π±,K±, or p(p̅ ). We see no evidence for signals and set upper limits on the branching fractions in the range (2.8–8.9)×10-5. If observed, these decays may display CP violating asymmetries.
