Polarization analysis in $e^{+} e^{-} \to J / ψ \to$ baryon-antibaryon pairs

Zhe Zhang, Tianbo Liu, Rong-Gang Ping +2

We present a comprehensive polarization analysis for the process $e^{+} e^{-} \to J / ψ \to$ baryon-antibaryon pairs~ $B_{1} B ˉ_{2}$ . All possible helicity amplitude…

Search for CP Violations in the Production and Decay of the Hyperon-Antihyperon Pairs

Mengjiao Guo, Zhe Zhang, Ronggang Ping +1

This study introduces a complete joint angular distribution analysis for the process $e^{+} e^{-} \to J / ψ \to B (\to B_{1} π) B ˉ (\to B ˉ_{1} π)$ with polarized beams, where $B$ and $…
