摘要：

We report results from a search for the decay B-s(0)->mu(+)mu(-) using 1.3 fb(-1) of p (p) over bar collisions at root 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 B(B-s(0)->mu(+)mu(-))< 1.2x10(-7) at the 95% C.L.
