Description

In this talk I give an experimental review of the current status of |V_ub| determinations. Precision measurements of charmless semileptonic B-decays allow for a determination of the magnitude of the CKM matrix element V_ub, for a test of the consistency of the CKM mechanism and potentially of NP scenarios. In this talk the various experimental methods to determine |V_ub| based on exclusive and inclusive measurements using tagged and untagged data samples are presented. The various contributions to the uncertainties on the |V_ub| measurements and the persistent disagreement between excl. and incl. |V_ub| results are discussed.
