Abstract

We report measurements of the decays B + → ϕ ϕ K + and B 0 → ϕ ϕ K 0 using a sample of 231 × 10 6 B ¯¯¯ B pairs collected with the BABAR detector at the PEP-II asymmetric-energy B factory at the Stanford Linear Accelerator Center. The branching fractions are measured to be B ( B + → ϕ ϕ K + ) = ( 7.5 ± 1.0 ( stat ) ± 0.7 ( syst ) ) × 10 − 6 and B ( B 0 → ϕ ϕ K 0 ) = ( 4.1 + 1.7 − 1.4 ( stat ) ± 0.4 ( syst ) ) × 10 − 6 for a ϕ ϕ invariant mass below 2.85     GeV / c 2 .
