Abstract

We report results on the Dalitz analysis of three-body charmless $B^{+} \to K^{+} π^{+} π^{-}$ and $B^{+} \to K^{+} K^{+} K^{-}$ decays based on a $140 {fb}^{- 1}$ data sample collected with the Belle detector. Measurements of branching fractions for quasi-two-body decays to scalar-pseudoscalar states: $B^{+} \to f_{0} (980) K^{+}$ , $B^{+} \to K_{0}^{*} (1430)^{0} π^{+}$ , and to vector-pseudoscalar states: $B^{+} \to K^{*} (892)^{0} π^{+}$ , $B^{+} \to ρ^{0} K^{+}$ , $B^{+} \to ϕ K^{+}$ are presented. Upper limits on decays to some pseudoscalar-tensor final states are reported. We also report the measurement of the $B^{+} \to χ_{c 0} K^{+}$ branching fraction in two $χ_{c 0}$ decays channels: $χ_{c 0} \to π^{+} π^{-}$ and $χ_{c 0} \to K^{+} K^{-}$ .
