THREE-BODY-DECAYS AT BELLE

We report branching fractions and CP asymmetries for three-body and semi-three-body decays observed at Belle. The results were obtained from a 414 fb^-1 data sample collected at the ϒ(4S) resonance, with the Belle detector at the KEKB asymmetric energy e⁺e^- collider. The first observation of B^± → ϕϕK^± and a study of related charmonium decays are presented. Additionally, we show the measurement of the semi-three-body decay B → ηK* and evidence for B → ηρ. We find no evidence for CP asymmetries in these modes.
