摘要	Branching fraction and asymmetry measurements of charmless B+-> K(+)h(1)(+)h(2)(-) (where h(1,2)=K, pi) decays are presented, using a data sample of 232x10(6) Upsilon(4S)-> B (B) over bar decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. Using a maximum likelihood fit, the following branching fraction results were obtained: B(B+-> K+K+K-)=(36.2 +/- 3.3 +/- 3.6)x10(-6) and B(B+-> K+pi(+)pi(-))=(75.3 +/- 6.0 +/- 8.1)x10(-6). Upper limits were set for B(B+-> K+pi K-+(-))< 11.8x10(-6) and B(B+-> K+K+pi(-))< 6.1x10(-6) at 90% confidence level. The charge asymmetries for the decays B+-> K+K+K- and B+-> K+pi(+)pi(-) were measured to be A(K)()KK=0.11 +/- 0.08 +/- 0.03 and A(K)(*)pi pi=0.07 +/- 0.07 +/- 0.04, respectively. The first error quoted on branching fraction and asymmetry measurements is statistical and the second systematic.
