Full analysis of CP violation induced by the decay angular correlations in four-body cascade decays of heavy hadrons
Zhen-Hua Zhang, Jian-Yu Yang, Xin-Heng Guo
The violation of the charge-parity (CP) transformation symmetry, which although has been observed in plenty of pure meson decay processes, was only confirmed just very recently by…

CP asymmetries corresponding to the imaginary parts of the interference terms in cascade decays of heavy hadrons
Jing-Juan Qi, Jian-Yu Yang, Zhen-Hua Zhang
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^\p…
