Title: Model-independent extraction of |V cb| from B ¯ D * ν -

We fit the unfolded data of $$-\atop{B}$$ 0→D *+ℓ$$-\atop{v}$$ from the Belle experiment, where ℓ ≡ e,μ, using a method independent of heavy quark symmetry to extrapolate to zero-recoil and extract the value of |V cb|. This results in |V cb| (41.9$$+2.0\atop{-1.9}$$) × 10 -3, which is robust to changes in the theoretical inputs and very consistent with the value extracted from inclusive semileptonic B decays.
