Measurements of Charmless Hadronic Two-Body B Meson Decays and the Ratio cal B(B--> DK)/ cal B(B--> D\pi)

TL;DR

This paper reports precise measurements of thirteen charmless hadronic B meson decay modes, including ratios of branching fractions, based on comprehensive data from the CLEO experiment, advancing understanding of B decay processes.

Contribution

The study provides the first detailed measurements of multiple charmless B decay modes and a new determination of the B->DK to B->Dpi branching ratio using the full CLEO data set.

Findings

Measured branching fractions for 13 B decay modes.

Set new limits on dibaryonic final states.

Determined the ratio BR(B->DK)/BR(B->Dpi).

Abstract

We present final measurements of thirteen charmless hadronic B decay modes from the CLEO experiment. The decay modes include the ten pipi, Kpi, and KKbar final states and new limits on dibaryonic final states, ppbar, pLambdabar, and LambdaLambdabar, as well as a new determination of the ratio BR(B-> DK)/BR(B-> Dpi). The results are based on the full CLEO II and CLEO III data samples totalling 15.3 fb-1 at the Upsilon(4S), and supercede previously published results.
