Semileptonic B Decays From BaBar: |V(Ub)| And |V(Cb)|

PDF Version Also Available for Download.

Description

The authors report results from the BABAR Collaboration on the semileptonic B decays, highlighting the measurements of the magnitude of the Cabibbo-Kobayashi-Maskawa matrix elements V{sub ub} and V{sub cb}. They describe the techniques used to obtain the matrix element |V{sub cb}| using the measurement of the inclusive B {yields} X{sub c}{ell}{nu} process and a large sample of exclusive B {yields} D*{ell}{nu} decays. The |V{sub ub}| matrix elements has been measured studying the hadronic mass distribution M{sub X} and the lepton spectra at the endpoint for the B {yields} X{sub u}{ell}{nu} process.
