Description

Rare beauty meson decays B_s,d to mu+mu- are searched in pp collisions at LHC using a data sample collected by the CMS experiment. These decays are highly suppressed in the standard model. They can only proceed through the flavor-changing neutral currents, which are forbidden at tree-level diagrams. These decays are an excellent probe to the new physics; any difference between the measured branching fraction and the standard model prediction could provide a smoking gun signal of new physics.
