Abstract:

We have searched a sample of 9.6 million BB̄ events for the lepton-flavor-violating decays B→he±μ±, B+→h-e-e+, B+→h-e+μ+, and B+→h-μ-μ+, where h is π, K, p, and K*(892), a total of sixteen modes. We find no evidence for these decays, and place 90% confidence level upper limits on their branching fractions that range from 1.0 to 8.3×10-6.

Abstract:

We present a search for the flavor-changing neutral current decay Bs→μ+μ-φ in pp̄ collisions at √s = 1.8 TeV, using 91 pb-1 of data collected at the Collider Detector at Fermilab (CDF). We find two candidate events for this decay, which are consistent with the background estimate of one event, and set an upper limit on the branching fraction of B(Bs→ μ+μ-φ)<6.7×10-5 at a 95% confidence level. This is the first limit on the branching fraction of this decay.
