Abstract

We report results from a search for the decay B0s→ μ+μ- using 1.3 fb-1 of pp̅ collisions at √ s = 1.96 TeV collected by the DO 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(B0s → μ+μ- ) < 1.2 x 10-7 at the 95% C.L.
