Abstract

Three-body B decays of heavy-flavoured hadrons into light particles are a natural source of CP violation. In order to explain those processes we have to understand the role of final-state interactions (FSI) and strong phases from the primary weak vertex. The gigantic samples of B and D decays collected by the LHCb, BES-III and, in the near future, Belle II experiments motivated theoretical efforts in the past decade towards building models that are based on more solid grounds. In this talk an overview some of this models with some examples how including FSI in amplitude analysis can help us understand the underlying mechanisms of the CP asymmetries pattern observed in the Dalitz plot.
