# Lattice QCD and the search for BSM signals in b physics

## Matthew Wingate (Cambridge University)

**Abstract**

In the past decade, unquenched lattice QCD calculations have increasingly
helped to test CKM unitarity, searching for hints of new physics. 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 give a brief review of the methods of lattice QCD and will present results of
ongoing unquenched lattice calculations of B to K* form factors.
