CP asymmetries corresponding to the imaginary parts of the interference terms in cascade decays of heavy hadrons

Abstract

A mechanism of generating CP violation through the imaginary part of the interference of two amplitudes is proposed. This mechanism has shown clear evidence in decays such as $B^{\pm }\to {\pi }^{\pm }{\pi }^{+}{\pi }^{-}$. The proposed mechanism is helpful in searching for CP violation in bottom and charmed baryon decay processes.
