Measurement of branching fraction and search for CP violation in B → ϕϕK
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 B¯B events. The data were recorded at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. For B+ → ϕϕK+, the branc...

| Zusammenfassung: | 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 B¯B events. The data were recorded at the Υ(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 ... respectively. Similarly, the branching fraction obtained for ... below the ηc threshold is ... . We also measure the CP-violation symmetry for ... within the ηc region ... .(ProQuest: ... denotes formulae omitted.) |
