- Abstract
- We report the measurement of branching fractions and CP-violation asymmetries in B -> phi phi K decays based on a 711 fb(-1) data sample containing 772 x 10(6) B (B) over bar events. The data were recorded at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+) e(-) collider. For B+ -> phi phi K+, the branching fraction and CP-violation asymmetry measured below the eta(c) threshold (m(phi phi) < 2.85 GeV/c(2)) are [3.43(-0.46)(+0.48) (stat) +/- 0.22(syst)] x 10(-6) and -0.02 +/- 0.11(stat) +/- 0.01(syst), respectively. Similarly, the branching fraction obtained for B-0 -> phi phi K-0 below the eta(c) threshold is [3.02(-0.66)(+0.75) (stat) +/- 0.20(syst)] x 10(-6). We also measure the CP-violation asymmetry for B+ -> phi phi K+ within the eta(c) region (m(phi phi) is an element of [2.94,3.02] GeV/c(2)) to be +0.12 +/- 0.12(stat) +/- 0.01(syst).
