Description

The recently measured first few moments of the q2 distribution in inclusive semi-leptonic B decays are of great interest for the extraction of |Vcb| from inclusive decays.
In this talk we review the theoretical calculation of the q2 moments and their inclusion into the global fit for the extraction of HQE parameters and |Vcb|.
We discuss the improvements and features of the fit, paying attention to the treatment of correlations.
Our updated value is |Vcb|=(41.97±0.48)×103.
