Abstract

We report results from a search for the decay Bs0 → μ+μ- using 1.3 fb-1 of pp̅ collisions at √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 Ɓ(Bs0 → μ+μ-) < 1.2 x 10-7 at the 95% C.L.
