Inclusive |V{sub ub}| Measurements at BABAR
- SLAC
We present two inclusive measurements of Cabibbo-Kobayashi-Maskawa (CKM) matrix element |V{sub ub}|: one uses the lepton energy spectrum (E{sub 1}) and the other uses the invariant mass of the hadronic system (m{sub x}) to discriminate signal ({bar B} {yields} X{sub u}{ell}{bar {nu}}) and background ({bar B} {yields} X{sub c}{ell}{bar {nu}}) events in {bar B} {yields} X{ell}{bar {nu}} transitions. Both analyses are based on data samples collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC.
