    Abstract:
    We report on a search for the flavor-changing neutral current decay D0-->µ+µ- in pp-bar collisions at sqrt[s]=1.96 TeV using 65 pb-1 of data collected by the CDF II experiment at the Fermilab Tevatron Collider. A displaced-track trigger selects long-lived D0 candidates in the D0-->µ+µ- search channel, the kinematically similar D0--> pi + pi - channel used for normalization, the Cabibbo-favored D0-->K- pi + channel used to optimize the selection criteria in an unbiased manner, and their charge conjugates. Finding no signal events in the D0-->µ+µ- search window, we set an upper limit on the branching fractionB(D0-- >µ+µ-)
