urn:hdl:2445/131405 Search for B meson decays to η′η′K Graugés Pous, Eugeni BABAR Collaboration Física de partícules Experiments Mesons (Física nuclear) Particle physics Experiments Mesons (Nuclear physics) We describe searches for decays of B mesons to the charmless final states η ′ η ′ K . The data consist of 228 × 10 6 B ¯¯¯ B pairs produced in e + e − annihilation, collected with the BABAR detector at the Stanford Linear Accelerator Center. The 90% confidence level upper limits for the branching fractions are B ( B 0 → η ′ η ′ K 0 ) < 31 × 10 − 6 and B ( B + → η ′ η ′ K + ) < 25 × 10 − 6 . 2019-04-04T12:49:20Z 2019-04-04T12:49:20Z 2006-08-14 2019-04-04T12:49:20Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/10.1103/PhysRevD.74.031105 Physical Review D, 2006, vol. 74, num. 3, p. 031105(R) https://doi.org/10.1103/PhysRevD.74.031105 (c) American Physical Society, 2006 info:eu-repo/semantics/openAccess American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
