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
