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.
