We present a new expected upper limit of the rare decay branching ratio B{sub s} {yields} {mu}{sup +}{mu}{sup -} using about 5 fb{sup -1} of Run II data collected with the D0 detector at the Tevatron. When setting limits on the branching ratio, selected events are normalized to reconstructed B{sup {+-}} {yields} J/{Psi}K{sup {+-}} events in order to decrease the systematic uncertainty. The resulting expected upper limit is {Beta}(B{sub s} {yields} {mu}{sup +}{mu}{sup -}) = 4.3(5.3) x 10{sup -8} at the 90% (95%) C.L.
