Description

This dissertation presents a measurement of the CKM matrix element |Vub| made with a sample of 64 million B(bar B) events collected with the BABAR detector. Using Heavy Quark theory, we combine the observed yield of leptons from semileptonic B decay in the electron energy interval 2.1-2.6 GeV with a recent CLEO measurement of the B → Xsγ photon spectrum to find |Vub| = (4.25 ± 0.35 ± 0.45 ± 0.20) x 10-3, where the first uncertainty is experimental and the last two are from theory
