Received 5 May 1999; published in the issue dated 25 October 1999
We report on a search for the flavor-changing neutral current decays B+→μ+μ-K+ and B0→μ+μ-K*0 using 88pb-1 of data from p̅ p collisions at √s = 1.8TeV, collected with the Collider Detector at Fermilab. Finding no evidence for these decays, we set upper limits on the branching fractions B(B+→μ+μ-K+)<5.2×10-6 and B(B0→μ+μ-K*0)<4.0×10-6 at the 90% confidence level.
