Polarized lepton beams control quantum discord and steering in hyperon-antihyperon pairs from e+e- annihilation, with discord persisting in separable states via transverse polarization.
Transverse polarization in e+e- collisions generates maximally entangled fermion pairs in QED processes and boosts entanglement in electroweak and Bhabha scattering.
Derives algebraic conditions under which an LHVT reproduces QFT angular correlations in ZZ leptonic decays, existing only for a unique state and restricted θ_W when w≠0.
