Abstract
We report results on a Dalitz analysis of three-body charmless B-+/--> K-+/-pi(+/-)pi(-/+) decay including searches for direct CP violation. We report the first observation of the decay B-+/--> f(2)(1270)K-+/- with a statistical significance above 6 sigma. We also observe first evidence for large direct CP violation in the B-+/-->rho(770)K-0(+/-) channel. The results are obtained with a data sample that contains 386x10(6) B (B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider.
