Determining the Spin Density Matrix via Its Rank and Probing the Quantum Entanglement and Bell Non-Locality at the Lepton Colliders

Liwei Liu, Xiqing Hao, Dianwei Wang +2

Considering two-fermion $F_{a} F_{b}$ productions and decays via one scalar or photon exchange at the $e^{+} e^{-}$ collider, we show that the rank $r_{I ¨} $ of spin density matrix $I ¨ $ is equ…

Determining the Spin-Analyzing Powers via Invariants of the Spin Correlation Matrices and Probing the Bell Non-Locality at the Lepton Colliders

Dianwei Wang, Xiqing Hao, Liwei Liu +2

We consider the two-fermion $F_{a} F_{b}$ productions and decays via one mediator exchange at the $e^{+} e^{-}$ collider. With the assumption that the spin is defined via the Lorentz symmet…
