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…

Polarization analysis of two baryons with various spin combinations produced in electron-positron annihilation

Zhe Zhang, Rong-Gang Ping, Tianbo Liu +3

We developed a method to analyze the polarization correlations of two baryons $B_{1} B ˉ_{2}$ with various spin combinations in the annihilation process. We established spin den…

Refined analysis of $Ω^{-} Ω ˉ^{+}$ polarization in electron-positron annihilation process

Zhe Zhang, Jiao Jiao Song, Ya-jin Zhou

We investigate the production of spin-3/2 hyperon pairs, $Ω^{-} Ω ˉ^{+}$ , in electron-positron annihilation within the helicity amplitude formalism. A refined selection of helicity b…

Spin Density Matrix for $Ω^{-}$ and its Polarization Alignment in $ψ (3686) \to Ω^{-} Ω ˉ^{+}$

Zhe Zhang, Jiao Jiao Song

We investigate the spin density matrix of $Ω^{-}$ in the Cartesian coordinate system of baryon-antibaryon pairs produced in $e^{+} e^{-}$ annihilation. Using the helicity formalism of…
