Determination of the B̄→D*ℓν̄ decay width and |V cb|

Abstract:

In the standard model, the charged current of the weak interaction is governed by a unitary quark mixing matrix that also leads to CP violation. Measurement of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements is essential to searches for new physics, either through the structure of the CKM matrix, or a departure from unitarity. We determine the CKM matrix element |V cb| using a sample of 3×10 6 BB̄ events in the CLEO detector at the Cornell Electron Storage Ring. We determine the yield of ...
