Abstract

We report on a search for Bs0μ+μ and Bd0μ+μ decays in pp¯ collisions at s=1.96TeV using 171pb1 of data collected by the CDF II experiment at the Fermilab Tevatron Collider. The decay rates of these rare processes are sensitive to contributions from physics beyond the standard model. One event survives all our selection requirements, consistent with the background expectation. We derive branching ratio limits of B(Bs0μ+μ)<5.8×107 and B(Bd0μ+μ)<1.5×107 at 90% confidence level.
