Spin entanglement and quantum correlations in hyperon–antihyperon production

We give a brief overview of spin entanglement and related quantum correlations in hyperon–antihyperon systems produced at high energies, with emphasis on channels accessible at [Formula: see text] colliders. Treating weak hyperon decays as generalized quantum spin measurements, we analyze the spin-density matrix, Bell inequalities, entanglement, steering and discord in [Formula: see text] and clarify the role of time-like electromagnetic form factors (EMFFs) in shaping these correlations.
