Search for the rare decay B0(s)---> phi mu+ mu- with the D0 detector
The authors present a search for the flavor-changing neutral current decay B{sub s}{sup 0} {yields} {phi}{mu}{sup +}{mu}{sup -} using about 0.45 fb{sup -1} of data collected in p{bar p} collisions at {radical}s = 1.96 TeV with the D0 detector at the Fermilab Tevatron Collider. They find an upper limit on the branching ratio of this decay normalized to B{sub s}{sup 0} {yields} J/{psi}{phi} of {Beta}(B{sub s}{sup 0} {yields} {phi}{mu}{sup +}{mu}{sup -})/{Beta}(B{sub s}{sup 0} {yields} J/{psi}{phi}) < 4.4 x 10{sup -3} at the 95% C.L. Using the central value of the world average branching fraction of B{sub s}{sup 0} {yields} J/{psi}{phi}, the limit corresponds to {Beta}(B{sub s}{sup 0} {yields} {phi}{mu}{sup +}{mu}{sup -}) < 4.1 x 10{sup -6} at the 95% C.L., the most stringent upper bound to date.
