Search for the Decay b -> Xs mu+ mu-
Abstract
We have searched for the flavor-changing neutral current decay b -> s mu+ mu- in p pbar collisions at sqrt(s) = 1.8 TeV with the DO detector at Fermilab. We determine the 90% confidence level limit for the branching fraction to be B(b -> Xs mu+ mu-) < 3.2 x 10-4. We argue that this limit is more stringent than the best published limit on this decay rate.
