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 productions and decays via one scalar or photon exchange at the collider, we show that the rank of spin density matrix is equal…
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 productions and decays via one mediator exchange at the collider. With the assumption that the spin is defined via the Lorentz symmet…
