We have searched for the b-flavored baryon decay ΛbJ / ψΛ0 in pp̅ collisions at sqrt[s]=1.8 TeV with the Collider Detector at Fermilab (CDF). In the J / ψΛ0 invariant-mass distribution we observe a flat distribution and a small number of events, consistent with no signal. Using the b-quark cross section measured by the CDF we put an upper limit on the b→Λb production fraction times the branching ratio Fb)BbJ / ψΛ0) of 0.50×10-3 at 90% confidence level.
