`Rare B decay form factors from Lattice QCD

Abstract: In the past decade, unquenched lattice QCD calculations have
increasingly helped to test CKM unitarity. While work continues to further
improve the precision of these tests, another avenue of exploration is opening
up: rare B decays. As LHC experiments more precisely measure FCNC decays, such
as B to K* plus either a photon or a lepton--anti-lepton pair, new theory
calculations are needed to test the Standard Model. This talk will present
ongoing unquenched lattice calculations of B to K* and Bs to phi form factors.
