DESCRIPTION:In the Standard Model the element |V_{ub}| of the Cabibbo-Koba
 yashi-Maskawa (CKM) quark-mixing matrix plays a critical role in tests of 
 the prediction of CP violation. In this seminar\, it will be presented a m
 easurement of partial branching fractions for inclusive charmless semilept
 onic decays\, B -> Xu l nu in limited regions of phase space and the corre
 sponding values of |V_{ub}|\, as extracted using several theoretical calcu
 lations. The analysis is based on a sample of 383 million Y(4S) decays int
 o B Bbar pairs collected with the BaBar detector at the PEP-II e+ e- stora
 ge rings. Events selection uses either the invariant mass M_X of the hadro
 nic system\, the invariant mass squared\, q^2\, of the lepton and neutrino
  pair\, the kinematic variable P_+ or one of their combinations.\n\nhttps:
