Proposal to measure diphoton entanglement at pp colliders via Bethe-Heitler conversion in the tracker, yielding simulated significances of 0.007σ for Higgs→γγ and 1.5σ for continuum q q̄→γγ at HL-LHC.
Proposes using hemispherical projections to reduce continuous momenta to qubits and Monte Carlo simulation of tau lepton production at electron colliders to assess phase-space non-separability via EPR correlations.
Phenomenological calculation of entanglement entropies in B0 → VV decays shows strong dependence on relative phases and a correlation with branching fractions that the authors link to weak and strong interaction dynamics.
A review summarizing advancements in probing quantum entanglement and Bell inequalities using high-energy particle colliders.
