Description
Recently published and preliminary Fermilab/MILC and HPQCD lattice QCD calculations of form factors for B -> pi l nu and Bs -> K l nu will be presented. In combination with existing experiment, these results generate a significant reduction in the error of Vub. I will also discuss plans to improve the lattice calculations, including the use of a fully relativistic b quark to eliminate matching errors and an effort to extend the kinematic range of validity of lattice simulations to smaller q^2.
