| ABSTRACT: |
We present recent results on semileptonic B decays
using data collected by the BaBar detector at the PEP-II
asymmetric-energy e+e- collider at the Stanford Linear
Accelerator Center. We report several measurements
including the product F(1)|V_cb| from B- -> D*0e-nu decays,
the B -> Xc l nu hadronic moments, the weak annihilation
in B0 -> Xu l nu decays, the partial branching fraction
of B -> Xu l nu events with hadronic tags and the
corresponding hadronic moments.
The CKM matrix element V_ub is extracted by using recent
theoretical calculations of phase space acceptances.
