Abstract

We report on a search for the flavor-changing neutral current decays B⁺→ μ⁺μ^-K⁺ and i>B⁰→ μ⁺μ^-K^*0 using 88 pb^-1 of data from p̅p collisions at √s =1.8 TeV, collected with the Collider Detector at Fermilab. Finding no evidence for these decays, we set upper limits on the branching fractions Ɓ(B⁺→ μ⁺μ^-K⁺) < 5.2 X 10^-6 and Ɓ(B⁺→ μ⁺μ^-K^*0) -6 at the 90% confidence level.
