Abstract

We have performed a search for

B_{s}^{0} \to μ^{+} μ^{-}

and

B^{0} \to μ^{+} μ^{-}

decays in

p \bar{p}

collisions at

\sqrt{s} = 1.96 TeV

using

2 {fb}^{- 1}

of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron Collider. The observed number of

B_{s}^{0}

and

B^{0}

candidates is consistent with background expectations. The resulting upper limits on the branching fractions are

B (B_{s}^{0} \to μ^{+} μ^{-}) < 5.8 \times 10^{- 8}

and

B (B^{0} \to μ^{+} μ^{-}) < 1.8 \times 10^{- 8}

at 95% C.L.
