Description
In this talk I will present the calculation of moments of the $q^2$ distribution in inclusive semileptonic $B$ decays with a lower cut on the dilepton invariant mass $q^2$, confirming known results. The theoretical predictions are then used in a global fit to moments of the spectrum of inclusive semileptonic $B$ decays, allowing the extraction of $|V_{cb}|$. The fit includes the recently measured $q^2$ moments, together with moments in the lepton energy and hadronic invariant mass. The uncertainty on the non-perturbative parameters and on $|V_{cb}|$ slightly decreases, yielding to the final value $|V_{cb}| = (41.97\pm0.48)\times 10^{-3}$.
