An upper bound on concurrence is derived for fixed local polarizations in two-qubit systems, saturated by pure states in some cases, and applied to show reduced maximal entanglement in polarized q qbar pairs from parity-violating Z decays.

Entanglement in ttbar production at lepton colliders is typically reduced by scalar mediators but shows sizable deviations in U(1)B-L and Randall-Sundrum models, positioning quantum-information observables as probes for new neutral interactions.

Polarization, Maximal Concurrence, and Pure States in High-Energy Collisions
An upper bound on concurrence is derived for fixed local polarizations in two-qubit systems, saturated by pure states in some cases, and applied to show reduced maximal entanglement in polarized q qbar pairs from parity-violating Z decays.

Disentangling new physics with quantum entanglement in $t\bar{t}$ production at future lepton colliders
Entanglement in ttbar production at lepton colliders is typically reduced by scalar mediators but shows sizable deviations in U(1)B-L and Randall-Sundrum models, positioning quantum-information observables as probes for new neutral interactions.
