Description
We present a set of measurements of semileptonic B meson charmless decays using the BABAR data set collected at the SLAC e+e- B-factory operating on the Upsilon(4S) resonance. This paper includes: the measurement of the branching fraction of the exclusive charmless semileptonic decay B->omega l nu, where l is either an electron or a muon, with the charged B meson recoiling against a tag B meson decaying in the charmed semileptonic modes B -> DXlnu; and studies of B -> rho l nu, pi l nu and eta(') l nu decays in which branching fractions and distributions in the momentum transfer squared are measured and used to determine the CKM matrix element |Vub|.
