Title: Measurement of |V(Ub)| Using Inclusing Semileptonic B Meson Decays

Abstract

This dissertation presents a measurement of the CKM matrix element |V{sub ub}| 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 {yields} X{sub s}{gamma} photon spectrum to find |V{sub ub}| = (4.25 {+-} 0.35 {+-} 0.45 {+-} 0.20) x 10{sup -3}, where the first uncertainty is experimental and the last two are from theory.
