dc.description.abstract Results of the search for the rare decay $$B_s^0 \to \mu^+ \mu^-$$ 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 $$p\bar{p}$$ 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 $$\cal{B}$$($$B_s^0 \to \mu^+ \mu^-$$) $$< 15 \times 10^{-9}$$ ($$12 \times 10^{-9}$$) at the 95\% (90\%) C.L.
