TL;DR
This paper reports on CLEO's recent measurements of semileptonic B decay spectra and branching fractions, along with a preliminary fit to spectral moments used to determine |V_cb| with high precision.
Contribution
It provides new experimental data and a combined spectral moment analysis to improve the determination of the CKM matrix element |V_cb|.
Findings
Measured inclusive semileptonic B decay spectra and branching fractions.
Performed a combined fit to spectral moments consistent with Heavy Quark Expansion.
Achieved a precise determination of |V_cb|.
Abstract
I present recent CLEO measurements of inclusive semileptonic B decay spectra and the branching fraction. I also report preliminary results from a combined fit to spectral moments, which are compared to expectations in the Heavy Quark Expansion and used to precisely determine |V_cb|.
