Abstract

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