摘要：
Long-distance resonant dynamics along with a sizeable weak phase present in multi-body charmless b-hadron decays leads to rich structures of CP violation as a function of the phase space. Amplitude analysis provides a deeper understanding of the mechanisms that generate strong phase variations, which are responsible for this effect. We present the amplitude analyses of B+ -> pi+K+K- and B-s(0) -> (KsK +/-)-K-0 pi(-/+) decays. For the former, CP asymmetries of the contributing quasi-two-body resonances are measured. Charmless b-baryon decays represent a promising opportunity to make a first observation of CP violation in the baryonic sector. We also present the most recent measurements of four-body charmless b-baryon decays performed by LHCb.
