Summary:

Results of the search for the rare decay B⁰_s → μ⁺μ^- using data collected by the D0 detector at the Fermilab Tevatron collider are presented. This analysis covers the full Run II data set, corresponding to approximately 10.4 fb^-1 of integrated luminosity in p ̄p collisions at a center of mass energy of 1.96 TeV. The analysis used new variables and a multivariate technique to improve the background reduction. After seeing fewer events than expected from background, a new Tevatron best observed limit was set on the branching fraction of the decay at B(B⁰_s→ μ⁺μ^-) < 15 x 10^-9 (12 x 10^-9) at the 95% (90%) C.L.
