Abstract

We present final measurements of 13 charmless hadronic B decay modes from the CLEO experiment. The decay modes include the ten ππ, Kπ, and KK final states and new limits on dibaryonic final states, pp̄, pΛ̄, and ΛΛ̄, as well as a new determination of the ratio β(B→DK)/β(B→Dπ). The results are based on the full CLEO II and CLEO III data samples totalling 15.3 fb-1 at the Y(4S), and supercede previously published results.
