We have searched for the flavor-changing neutral current decay b → Xs μ+ μ- in pp̄ collisions at √s = 1.8 TeV with the DØ detector at Fermilab. We determine the 90% confidence level limit for the branching fraction to be B(b → Xs μ+ μ-) < 3.2 × 10-4. We argue that this limit is more stringent than the best published limit on this decay rate.
