We report results on the Dalitz analysis of three-body charmless B+→K+π+π- and B+→K+K+K- decays based on a 140fb-1 data sample collected with the Belle detector. Measurements of branching fractions for quasi-two-body decays to scalar-pseudoscalar states: B+→f0(980)K+, B+→K0*(1430)0π+, and to vector-pseudoscalar states: B+→K*(892)0π+, B+→ρ0K+, B+→ K+ are presented. Upper limits on decays to some pseudoscalar-tensor final states are reported. We also report the measurement of the B+→χc0K+ branching fraction in two χc0 decays channels: χc0→π+π- and χc0→K+K-. © 2005 The American Physical Society.
