Abstract
The CKM matrix element amplitude |V_cb| was determined using the data collected by the BABAR detector. The partial branching fraction, lepton-energy moments, and hadron-mass moments were measured in inclusive semileptonic decays B -> X_c l nu. A global fit to a Heavy-Quark-Expansion calculation allowed precise determination of |V_cb|, m_b, m_c, B(B -> X_c l nu) and four non-perturbative parameters.
