abstract
We report results on the Dalitz analysis of three-body charmless B+=>K+Pi+Pi- and B+=>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+ => f0(980)K+, B+ => K*_0(1430)^0 Pi+, and to vector-pseudoscalar states: B+ => K*(892)^0 Pi+, B+ => rho(770)K+, B+ => phi(1020)K+ are presented. Upper limits on decays to some pseudoscalar-tensor final states are reported. We also report the measurement of the B+ => chi_c0 K+ branching fraction in two chi_c0 decays channels: chi_c0 => Pi+Pi- and chi_c0 => K+K-.

Systematic Analysis of $B_s \to SP$ Decays in Perturbative QCD Approach
