Abstract

We report results on a Dalitz analysis of three-body charmless B±→K±π±π decay including searches for direct CP violation. We report the first observation of the decay B±→f2(1270) K± with a statistical significance above 6σ. We also observe first evidence for large direct CP violation in the B±→ρ(770) 0K± channel. The results are obtained with a data sample that contains 386×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider.
