Abstract

The magnitude of the CKM matrix element |Vub| is determined by measuring the inclusive charmless semileptonic branching fraction of beauty hadrons at OPAL based on b → Xuℓv event topology and kinematics. This analysis uses OPAL data collected between 1991 and 1995, which correspond to about four million hadronic Z decays. We 1easure Br(b → Xuℓv) to be (1.63 ± 0.53 +0.55 -0.62) × 10-3. The first uncertainty is the statistical error and the second is the systematic error. From this analysis, |Vub| is determined to be: |Vub| = (4.00 ± 0.65(stat)+0.67 -0.76(sys) ± 0.19(HQE)) × 10-3. The last error represents the theoretical uncertainties related to the extraction of |Vub| from Br(b → Xuℓv) using the Heavy Quark Expansion.

N2 - The magnitude of the CKM matrix element |Vub| is determined by measuring the inclusive charmless semileptonic branching fraction of beauty hadrons at OPAL based on b → Xuℓv event topology and kinematics. This analysis uses OPAL data collected between 1991 and 1995, which correspond to about four million hadronic Z decays. We 1easure Br(b → Xuℓv) to be (1.63 ± 0.53 +0.55 -0.62) × 10-3. The first uncertainty is the statistical error and the second is the systematic error. From this analysis, |Vub| is determined to be: |Vub| = (4.00 ± 0.65(stat)+0.67 -0.76(sys) ± 0.19(HQE)) × 10-3. The last error represents the theoretical uncertainties related to the extraction of |Vub| from Br(b → Xuℓv) using the Heavy Quark Expansion.
