Cp Violation in B Decays:. the Role of Final-State Interactions

The main goals of the programme of studying CP violation in B decays are briefly presented. It is stressed that reliable ways of handling final-state interactions have to be found if these goals are to be achieved. On the example of B⁰ -> Kbar K decays it is shown that rescattering may strongly affect phases of decay amplitudes. The need to understand SU(3) breaking effects is also pointed out.
