Description
Measurements of rare B meson decay properties provide an alternative approach to direct searches for physics beyond the Standard Model. These decays, which proceed through flavor-changing neutral currents, can have interferences from new physics through loop diagrams. In particular, the angular distribution of the decay B to K(*) mu+mu- can be measured as a function of the square of the dimuon invariant mass, an excellent probe to possible new physics scenarios. This talk presents the forward-backward asymmetries of the muons, the K* longitudinal polarization fractions and the differential branching fractions, measured with data recorded by the CMS experiment.
