Model-independent extraction of |Vcb| from B¯→D⁎ℓν‾

We fit the unfolded data of B¯0→D⁎+ℓν‾ 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 |Vcb|. This results in |Vcb|=(41.9−1.9+2.0)×10−3, which is robust to changes in the theoretical inputs and very consistent with the value extracted from inclusive semileptonic B decays.
