Polarization transfer in $\ddot{I}{ˆ}^{\prime }\to \ddot{I}ˆ\ddot{I}€\ddot{I}€$: a complete spin density matrix analysis framework

Jiabao Gong, Guanyu Wang, Dongyu Yuan +7

A theoretical framework based on the Spin Density Matrix (SDM) formalism is developed to describe polarization transfer in the decay chain $e^+e^- \rightarrow ψ^\prime \rightarrow…
