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…

$C P$ violation for $B^{0} \to ρ^{0} (ω) ρ^{0} (ω) \to π^{+} π^{-} π^{+} π^{-}$ in QCD factorization

Gang Lü, Jia-Qi Lei, Xin-Heng Guo +2

In the QCD factorization (QCDF) approach we study the direct $C P$ violation in $B ˉ^{0} \to ρ^{0} (ω) ρ^{0} (ω) \to π^{+} π^{-} π^{+} π^{-}$ via the $ρ - ω$ mixing mechanism. We find t…
