Abstract

We report results from a search for the decay B_s⁰ → 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(B_s⁰ → μ⁺μ^-) < 1.2 x 10^-7 at the 95% C.L.
