Abstract

Lattice QCD can contribute to the search for new physics in b -> s decays by providing first-principle calculations of B -> K(*) form factors. Preliminary results are presented here which complement sum rule determinations by being done at large q² and which improve upon previous lattice calculations by working directly in the physical b sector on unquenched gauge field configurations.
