Measurements of the CKM matrix element vertical bar Vub vertical bar with BABAR
Creators
Description
A preliminary BABAR measurement of the inclusive partial branching fraction b → ueν is presented. We find ΔB(b → ueν, 2.3...2.6 GeV) = (0.152 ± 0.014stat. ±0.014syst.) x 10-3. In addition, a preliminary measurement of the branching fraction B → ρeν is presented and the CKM matrix element vertical bar Vub vertical bar is determined from tis measurement. We find B(B0 → ρ- e+ ν) = (3.39 ± 0.44stat. ± 0.52syst. ± 0.60theo.) x 10-4, and vertical bar Vub vertical bar = (3.69 ± 0.23stat.± 0.27syst.-0.59theo.+0.40)x10-3
