Abstract

We present a search for the flavor-changing neutral current decays

B_{d}^{0} \to μ^{+} μ^{-}

and

B_{s}^{0} \to μ^{+} μ^{-}

p \bar{p}

collisions at

\sqrt{s} = 1.8

TeV, using

98 {pb}^{- 1}

of data collected at the Collider Detector at Fermilab. We find one candidate event for these decays, which is consistent with the background estimates, and set upper limits on the branching fractions of

B {(B}_{d}^{0} \to μ^{+} μ^{-}) < 8.6 \times 10^{- 7}

and

B {(B}_{s}^{0} \to μ^{+} μ^{-}) < 2.6 \times 10^{- 6}

at 95% confidence level.
