Abstract

We report on a study of three-body charmless decays B+→K+h+h- based on a 29.1 fb-1 data sample collected with the Belle detector. With no assumptions on the intermediate mechanisms, the following three-body branching fractions have been measured for the first time: β(B+→K+π-π+) =(55.6±5.8 ±7.7) × 10-6 and β(B+→K+K-K+) =(35.3±3.7±4.5) × 10-6. We present the first observation of the decay B+→f0(980)K+ with a branching fraction product of β(B+→f0(980)K+) × β(f0(980)→π+π-) =(9.6+2.5+1.5+3.4-2.3-1.5-0.8) × 10-6. This is the first reported example of a B meson decay to a scalar pseudoscalar final state. We also report the first observation of B+→K*(892)0π+ decay with a branching fraction of β(B+ →K*(892)0π+)=(19. 4+4.2+2.1+3.5-3.9-2.1-6.8) × 10-6.
