N2 - We report on form factors for the B → Kl+l- semi-leptonic decay process. We use several lattice spacings from a = 0.12 fm down to 0.06 fm and a variety of dynamical quark masses with 2+1 flavors of asqtad quarks provided by the MILC Collaboration. These ensembles allow good control of the chiral and continuum extrapolations. The b-quark is treated as a clover quark with the Fermilab interpretation. We update our results for fk and f, or, equivalently, f+ and f0. In addition, we present new results for the tensor form factor fT . Model independent results are obtained based upon the z-expansion.
