Abstract
Observations are reported of different sources of violation from an amplitude analysis of decays, based on a data sample corresponding to an integrated luminosity of of collisions recorded with the LHCb detector. A large asymmetry is observed in the decay amplitude involving the tensor resonance, and in addition significant violation is found in the wave at low invariant mass. The presence of violation related to interference between the S wave and the wave amplitude is also established; this causes large local asymmetries but cancels when integrated over the phase space of the decay. The results provide both qualitative and quantitative new insights into -violation effects in hadronic decays.
