摘要：

We report results of a study of charmless B meson decays to three-body Kpipi, KKpi and KKK final states. Measurements of branching fractions for B decays to K(+(0))pi(+)pi(-), K+K+K-, (KK+K-)-K-0, (K+KSKS0)-K-0 and (KSKSKS0)-K-0-K-0 final states are presented. The decays B-0-->(KK+K-)-K-0, B+-->(K+KSKS0)-K-0 and B-0-->(KSKSKS0)-K-0-K-0 are observed for the first time. We also report evidence for B+-->K(+)K(-)pi(+) decay. For the three-body final states K(0)K(+)pi(-), K(S)(0)K(S)(0)pi(+), K(+)K(+)pi(-) and K(-)pi(+)pi(+), 90% confidence level upper limits are reported. Finally, we discuss the possibility of using the three-body B-0-->(KSK+K-)-K-0 decay for CP violation studies. The results are obtained with a 78 fb(-1) data sample collected at the Y(4S) resonance by the Belle detector operating at the KEKB asymmetric energy e(+)e(-) collider.
