Abstract

We report on a search for Bs0→μ+μ- and Bd0→μ+μ- decays in pp̅ collisions at √s=1.96 TeV using 364 pb-1 of data collected by the CDF II detector at the Fermilab Tevatron Collider. After applying all selection requirements, we observe no candidates inside the Bs0 or Bd0 mass windows. The resulting upper limits on the branching fractions are B(Bs0→μ+μ-)<1.5×10-7 and B(Bd0→μ+μ-)<3.9×10-8 at 90% confidence level.
