Abstract

We present a search for the flavor-changing neutral current decay Bs0→ μ +μ - using about 0.45fb -1 of data collected in pp̄ collisions at √s=1.96TeV with the D0 detector at the Fermilab Tevatron Collider. We find an upper limit on the branching ratio of this decay normalized to Bs0→J/ψ of B(Bs0→ μ +μ -)B(Bs0→J/ψ)<4.4×10 -3 at the 95% C.L. Using the central value of the world average branching fraction of Bs0→J/ψ, the limit corresponds to B(Bs0→ μ +μ -)<4.1×10 -6 at the 95% C.L., the most stringent upper bound to date. © 2006 The American Physical Society.
