Abstract:
Using the CLEO-III detector at CESR we study e+e- collisions in the center-of-mass energy close to, or above, Λ b 0Λ̄b 0 production threshold. We search for evidence of Λb 0Λ̄b 0 resonance production and set upper limits based on inclusive hadron production as a barometer of Λb 0Λ̄b 0 production. © 2005 The American Physical Society.
