Abstract
We report on a search for the flavor-changing neutral current decay in collisions at using of data collected by the CDF II experiment at the Fermilab Tevatron Collider. A displaced-track trigger selects long-lived candidates in the search channel, the kinematically similar channel used for normalization, the Cabibbo-favored channel used to optimize the selection criteria in an unbiased manner, and their charge conjugates. Finding no signal events in the search window, we set an upper limit on the branching fraction at the (95%) confidence level.
