Disentangling isospin violation in charmonia decaying into $Ξ Ξ$ pairs

Huan-Ran Wen, Chun-Qiu Zhao, Xu Cao +1

Based on a model-independent isospin decomposition, we perform a data-driven analysis of $J / ψ$ and $ψ (2 S)$ decays into $Ξ Ξ ˉ$ pairs by leveraging the full set of observables from…

Spin density matrix of baryon-antibaryon pairs in electron-positron annihilation with $P$ and $C P$ violation including electron mass

Chun-Qiu Zhao, Xu Cao, Jian-Ping Dai

In the center-of-mass frame, the spin density matrix for octet baryon-antibaryon pairs produced in polarized electron-positron annihilation is unambiguously determined within the o…
