Description
We present recent results on the extraction of Vcb from data on B->D^* l nu decays. Using two different parameterizations of form factors, we show how theory input from Heavy Quark Effective Theory or Light Cone Sum Rules affect the value of Vcb. The results show that the inconsistency of Vcb extractions in exclusive and inclusive decays needs a reappraisal.
