`Finding New Physics with B decays: prospects for B to K* mu+mu-'

Abstract: I will review the search for New Physics (NP) with B
decays. I will focus on the rare decay B to K* mu+mu-, as it is
regarded as one of the crucial channels for B physics. This is because
polarization of the K* allows a precise angular reconstruction
resulting in many observables that offer new important tests of the
Standard Model and its extensions. I then show that some of these
observables have small to moderate dependence on hadronic quantities
and high sensitivity to New Physics. I will then review the prospects
for this channel at LHCb, and highlight three observables which are
suitable for an early measurement. I will finally show how such
measurements could have a large impact on the parameter space
available for NP contributions to the Wilson coefficients for some key
flavour-changing effective operators.
