David Lopes Pegna (for the BaBar collaboration)
TL;DR
This paper reports measurements of exclusive B meson decays to charm states and determines the CKM matrix element |Vcb| using data from the BaBar experiment at the Upsilon(4S) resonance.
Contribution
It provides new experimental results on B -> Xc l nu decays and a precise measurement of |Vcb| from the BaBar collaboration.
Findings
Measured branching fractions of exclusive B -> Xc l nu decays.
Determined |Vcb| with improved precision.
Compared results with theoretical predictions.
Abstract
We present recent results on exclusive Bbar -> Xc l- nubar_l decays and measurements of the CKM matrix element |Vcb| based on data collected at the Upsilon(4S) resonance with the babar detector at the PEP-II e+e- storage rings.
