Abstract

Results on Dalitz analysis of three-body charmless B+=>K+pi+pi- and B+=>K+K+K- decays are reported. We also present preliminary results on the studies of direct CP violation in three-body decay B+-=>K+-pi+pi-. The analysis is performed using a large data sample collected with the Belle detector.
