Resumo

We propose a theoretical framework to understand the observable global charge-parity (CP) violation in charmless three-body B +/- decays. The decay amplitudes consider the effects of the pi pi -> K K rescattering treated within a CPT invariant framework together with the U-spin symmetry relation, s <-> d, which results pi <-> K in the final state. This approach applied to a two-channel model provides the magnitudes and signs of the ratios of the global CP asymmetries for B +/- -> K +/-pi+pi-, B +/- -> K +/- K+K-, B +/--> pi +/- K+K-, and B +/- -> pi +/-pi+pi- decays, qualitatively consistent with those obtained from the available experimental data. In addition, by considering the neutral channels, we predict the ratios for the global CP asymmetries for these decays. (c) 2021 The Author(s). Published by Elsevier B.V.
