We present the results of a search for the flavor-changing neutral current decay B0_s -> mu+ mu- using approximately 6.1 fb^{-1} of p anti-p collisions at sqrt{s}=1.96 TeV collected by the D0 experiment at the Fermilab Tevatron Collider. Compared to the previous published D0 result we have increase the amount of data analysed by a factor of 4 and improved the background rejection using a multivariate discrimination technique.
