We report on a search for the flavor-changing neutral current decay D 0→μ+μ- in pp̄ collisions at √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 D 0→π+π- channel used for normalization, the Cabibbo-favored D0K-π- 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 fraction B(D0→μ+μ-)≤2. 5× 10-6 (3.3× 10-6) at the 90% (95%) confidence level.
