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