Abstract

We report on a search for the flavor-changing neutral current decays

B_{d, s}^{0} \to μ^{+} μ^{-}

B^{+} \to μ^{+} μ^{-} K^{+}

, and

B^{0} \to μ^{+} μ^{-} K^{* 0}

using data from

p \bar{p}

collisions at

\sqrt{s} = 1.8 TeV

, collected with the Collider Detector at Fermilab during the 1992–1993 running period. We find no indication of such decays, and we set the following 90% confidence level upper limits on branching ratios:

B (B^{0} \to μ^{+} μ^{-}) < 1.6 \times 10^{- 6}

B (B_{s}^{0} \to μ^{+} μ^{-}) < 8.4 \times 10^{- 6}

B (B^{+} \to μ^{+} μ^{-} K^{+}) < 1.0 \times 10^{- 5}

, and

B (B^{0} \to μ^{+} μ^{-} K^{* 0}) < 2.5 \times 10^{- 5}
