Search for B meson decays to η′η′K
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 fr...

| Sumario: | 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 . |
