| dc.description | We report on the search for $B^0_s\toμ^+μ^-$, $B^0_d\toμ^+μ^-$ decays and $b\to s μ^+μ^-$ transitions in exclusive decays of B mesons using the CDF II detector at the Fermilab Tevatron Collider. Using 2 fb$^{-1}$ of Run II data we find upper limits on the branching fractions $\mathcal{B}(B^0_s\toμ^+μ^-)<5.8\times 10^{-8}$ and $\mathcal{B}(B^0_d\toμ^+μ^-)<1.8\times 10^{-8}$ at 95% confidence level. The results for the branching fractions of the $b\to s μ^+μ^-$ transitions using 924 pb$^{-1}$ of Run II data are $\mathcal{B}(B^+\toμ^+μ^-K^+)=(0.60\pm0.15\pm0.04)\times 10^{-6}$, $\mathcal{B}(B^0_d\toμ^+μ^-K^{*0})=(0.82\pm0.31\pm0.10)\times 10^{-6}$ and $\mathcal{B}(B^0_s\to μ^+μ^-ϕ)/\mathcal{B}(B^0_s\to J/ψϕ) < 2.61\times 10^{-3}$ at 95% confidence level. | |
