We report measurements of the decays B+->phi phi K+ and B-0 ->phi phi K-0 using a sample of 231x10(6) B (B) over bar 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+->phi phi K+)=(7.5 +/- 1.0(stat)+/- 0.7(syst))x10(-6) and B(B-0 ->phi phi K-0)=(4.1(-1.4)(+1.7)(stat)+/- 0.4(syst))x10(-6) for a phi phi invariant mass below 2.85 GeV/c(2).

Abstract

We report measurements of the decays B+->phi phi K+ and B-0 ->phi phi K-0 using a sample of 231x10(6) B (B) over bar 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+->phi phi K+)=(7.5 +/- 1.0(stat)+/- 0.7(syst))x10(-6) and B(B-0 ->phi phi K-0)=(4.1(-1.4)(+1.7)(stat)+/- 0.4(syst))x10(-6) for a phi phi invariant mass below 2.85 GeV/c(2).
