Abstract:

The flavor-changing neutral current decay Bs --> mu+ mu- is a very sensitive probe to physics beyond the Standard Model. The predicted branching ratio in the Standard Model is on the order of 10^-9; beyond the sensitivity of the current experiments. However, in many extensions of the Standard Model, the branching ratio is naturally enhanced by one to three orders of magnitude and thus would be observable at the Tevatron. In this talk, I will discuss the experimental challenges of searching for rare B decays in a hadron collider environment and present the status and prospect of searching for Bs(d) --> mu+ mu- and other rare decays at CDF.
