Dalitz analysis of B → Khh decays at Belle

Garmash A.

We report results on the Dalitz analysis of three-body charmless B + → K+π+π-, B0 → K0π+π- and B+ → K+K+K- decays including searches for direct CP violation in B+ → K+π+π- mode. Branching fractions for a number of quasi-two-body intermediate states are reported. We also observe 3.9σ evidence for a large direct CP violation in B± → ρ(770)0K± channel. This is the first evidence for CP violation in a charged meson decay. The results are obtained using Dalitz analysis technique with a large data sample of BB̄ pairs collected with the Belle detector operating at the KEKB asymmetric energy e+e- collider. © 2006 American Institute of Physics.
