TL;DR
This paper measures the branching fraction of charmless inclusive B decays to eta' mesons with high momentum, providing insights into B decay mechanisms and contributing to understanding CP violation.
Contribution
It reports the first measurement of the charmless inclusive B -> eta'X branching fraction in a specific momentum range using a large data sample from CLEO detectors.
Findings
Br(B -> eta'X_(nc)) = (4.6 +- 1.1 +- 0.4 +- 0.5) x 10^(-4)
Measurement performed with 9.7 million BBbar pairs
Results help constrain theoretical models of B decays
Abstract
Based on a measurement of high momentum eta' production in B decays, we determine the charmless inclusive B -> eta'X_(nc) branching fraction in the lab-frame momentum interval 2.0<P_eta'<2.7 GeV/c. Using 9.7x10^6 BBbar pairs collected at the Upsilon(4S) center-of-mass energy with the CLEO II and II.V detector configurations, we find Br(B -> eta'X_(nc)) = (4.6 +- 1.1 +- 0.4 +- 0.5)x 10^(-4) in the 2.0<P_(eta')<2.7 GeV/c momentum range, where the uncertainties are statistical, systematic, and from subtraction of background from B decays to charm, respectively.
