Abstract

In an experiment to measure multimuon final states in interactions of 225-GeV/c π- with nuclear targets we have observed 65 900 Jψ→μ+μ- decays, of which 487 are accompanied by a third muon. We have used this sample to search for production of bottommeson pairs, followed by the decays B→Jψ+X, B̄→μ+X. We find, supposing linear A dependence, that σ(BB̄)<8 nb/nucleon with 90% confidence. This limit is in contradiction with a recent report that σ(BB̄)200 nb/nucleon.
