Study of B meson decays to three-body charmless hadronic final states
We report results of a study of charmless B meson decays to three-body Kππ, KKπ and KKK final states. Measurements of branching fractions for B decays to K= +(0)π +π -, K +K +K -, K 0K +K -, K +K s 0K s 0 and K s 0K s 0K s 0 final states are presented. The decays B 0→K 0K +K -, B +→K +K s 0K s 0 and B 0→K s 0K s 0K s 0 are observed for the first time. We also report evidence for B +→K +K -π + decay. For the three-body final states K 0K +π -, K s 0K s 0π +, K +K +π - and K -π +π +, 90% confidence level upper limits are reported. Finally, we discuss the possibility of using the three-body B 0→K s 0K +K - 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. © 2004 The American Physical Society.
