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…

Decay-angular-distribution correlated $C P$ violation in heavy hadron cascade decays

Yu-Jie Zhao, Zhen-Hua Zhang, Xin-Heng Guo

$C P$ violation in baryon decay processes is still undiscovered to date. We present a general analysis of the decay-angular-distributions and the corresponding $C P$ asymmetries…

The pollution to the $K π$ -puzzle from the isospin-breaking $π^{0} - η - η^{'}$ mixing effect

Zhen-Hua Zhang

The influence of the isospin-breaking $π^{0} - η - η^{'}$ mixing effect on the $C P$ -asymmetries of $B \to K π$ processes is examined for the first time. It is found that this mixing…

Probing the mass degeneracy of particles with different spins

Z. -H. Zhang, G. Lü, K. -W. Wei

The spin is an important property of a particle. Although it is unlikely to happen, there is still a possibility that two particle with different spins share similar masses. In thi…
