CP violation and CPT invariance in B+- decays with final state
interactions    [PDF]

I. Bediaga, T. Frederico, O. Lourenço

We show that final state interactions together with CPT invariance can play an important role in the recent observation of CP violation in three-body charmless B decays. A significant part of the observed CP asymmetry distribution in the Dalitz plot is located in a region where hadronic channels are strongly coupled. We assume that this CP violation distribution is basically due to the interference of two CP-conserving hadron-hadron amplitudes separated by a CP-noninvariant weak phase. We illustrate our discussion comparing the recent observation of CP violation in the B+-\to K+-K+K- and B+-\to K+-{\pi}+{\pi}- phase space, with a calculation based on {\pi}{\pi}\to KK scattering.
