- Abstract
- We report the measurement of branching fractions and CP-violation asymmetries in B→φφK decays based on a 711 fb-1 data sample containing 772×106 BB¯ events. The data were recorded at the I(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. For B+→φφK+, the branching fraction and CP-violation asymmetry measured below the ηc threshold (mφφ<2.85 GeV/c2) are [3.43-0.46+0.48(stat)±0.22(syst)]×10-6 and -0.02±0.11(stat)±0.01(syst), respectively. Similarly, the branching fraction obtained for B0→φφK0 below the ηc threshold is [3.02-0.66+0.75(stat)±0.20(syst)]×10-6. We also measure the CP-violation asymmetry for B+→φφK+ within the ηc region (mφφ[2.94,3.02] GeV/c2) to be +0.12±0.12(stat)±0.01(syst). © 2021 authors. Published by the American Physical Society.
