We report results from a search for the decay Bs0-->µ+µ- using 1.3 fb-1 of p[overline p] collisions at sqrt(s)=1.96 TeV collected by the D0 experiment at the Fermilab Tevatron Collider. We find two candidate events, consistent with the expected background of 1.24±0.99, and set an upper limit on the branching fraction of [script B](Bs0-->µ+µ-)<1.2×10-7 at the 95% C.L.
