The B → D*ℓν form factor at zero recoil and the determination of |Vcb|
/ Authors
/ Abstract
We describe a model independent lattice QCD method for determining the zero recoil form factor, h A 1 (1), for the semileptonic decay B → D * lν. We find , where uncertainties, respectively, are from statistics and fit procedures, matching of lattice theory to QCD, residual lattice spacing dependence, spectator quark mass effects and effects due to working in quenched lattice QCD.
