| Abstract | |
Resonances and final state interactions (FSI) play a role in the formation of charge parity (CP) violation (CPV) constrained by CPT invariance. We provide a general formulation of CPV including resonances and FSI starting from the CPT constraint. Our discussion is elaborated within a simple B decay model with the rho and f(0)(980) resonances plus a nonresonant background including the pi pi -> KK coupled amplitude. We consider a few illustrative examples to show the interference patterns appearing in the CP asymmetry, namely, that from the. resonance plus a nonresonant amplitude, and that from the interference of the. and f (0)(980) resonances. We perform the fit of the CP asymmetry for the charmless three-body B-+/- decay channel B+ -> pi(+)pi(+)pi(-) and obtain as outcome the B+ -> pi+K+K- for pp channel asymmetry in the mass region below 1.6 GeV in fair agreement with the new LHCb data. Analogously, we also describe the CP asymmetry of the B-+/- -> K-+/-pi(+)pi(-) decay, with that from the B-+/- -> (KK+K-)-K-+/- channel obtained as output. As in the previous case, we also found agreement with LHCb experimental data. (AU) | |
