Abstract
Measurements of asymmetries in charmless three-body decays of mesons are reported using proton-proton collision data collected by the LHCb detector, corresponding to an integrated luminosity of . The previously observed asymmetry in decays is confirmed, and asymmetries are observed with a significance of more than five standard deviations in the and decays, while the asymmetry of decays is confirmed to be compatible with zero. The distributions of these asymmetries are also studied as a function of the three-body phase space and suggest contributions from rescattering and resonance interference processes. An indication of the presence of the decays in both and decays is observed, as is violation involving these amplitudes.
