Beam-polarization-enabled witness of four-dimensional entanglement in $Ω^{-} Ω ˉ^{+}$ pairs

Qiu-Yan Zhang, Peng-Cheng Hong, Wei-Min Song

We study the entanglement structure of $Ω^{-} Ω ˉ^{+}$ pairs produced in $e^{+} e^{-} \to ψ (3686)$ , focusing on whether the entanglement requires the full four-dimensional spin space of each…

Bell nonlocality and entanglement in $χ_{c J}$ decays into baryon pair

PengCheng Hong, RongGang Ping, WeiMin Song

We present a systematic analysis of Bell nonlocality and entanglement in $χ_{c J}$ ( $J = 0, 1, 2$ ) decays into baryon pair( $B B ˉ$ ), with particular emphasis on their production via t…

Study of $P$ and $C P$ symmetries in $Ξ_{c}^{+} \to Ξ^{-} π^{+} π^{+}$ at electron-positron collider

Yunlu Wang, Yunlong Xiao, Pengcheng Hong +1

Symmetry studies represent one of the most promising frontiers in particle physics research. This investigation focuses on exploring $P$ and $C P$ symmetries in the charm system thr…
