摘要：

We have searched for the flavor-changing neutral current decay b --> X-s mu(+)mu(-) in <p(p)over bar> collisions at root s = 1.8 TeV with the D0 detector at Fermilab. We determine the 90% confidence level limit for the branching fraction to be B(b --> X-S mu(+)mu(-)) < 3.2 X 10(-4). We argue that this limit is more stringent than the best published limit on this decay rate. (C) 1998 Elsevier Science B.V.
