No events are observed and we set the following 90% C.L. upper limits on the branching fraction products: B (τ- → e- f0 (980)) × B (f0 (980) → π+ π-) < 3.2 × 10- 8 and B (τ- → μ- f0 (980)) × B (f0 (980) → π+ π-) < 3.4 × 10- 8. This is the first search performed for these modes. © 2009 Elsevier B.V.CollisionsBelleIdentificationSimulationModelsJetsKekbtext::journal::journal article::research article
