Abstract

We present measurements of branching fractions and charge asymmetries for charmless B-meson decays to three-body final states of charged pions and kaons. The analysis uses 81.8 fb(-1) of data collected at the Y(4S) resonance with the BABAR detector at the SLAC PEP-II asymmetric B Factory. We measure the branching fractions pi(+)pi(-)pi(+))=(10.9 +/- 3.3 +/- 1.6)x10(-6), B(B+-> K+pi(-)pi(+))=(59.1 +/- 3.8 +/- 3.2)x10(-6), and B(B+-> K+K-K+)=(29.6 +/- 2.1 +/- 1.6)x10(-6) and provide 90% C.L. upper limits for other decays. We observe no charge asymmetries for these modes.
