Abstract
We present the results of a search for the flavor-changing neutral current decay using a data set with integrated luminosity of of collisions at collected with the D0 detector in run II of the Fermilab Tevatron collider. We find the upper limit on the branching fraction to be at the 95% C.L. assuming no contributions from the decay in the signal region. This limit is the most stringent upper bound on the branching fraction to date.
