Recent proposals to test Bell's inequalities with entangled pairs of pseudoscalar mesons are reviewed. This includes pairs of neutral kaons or B-mesons and offers some hope to close both the locality and the detection loopholes. Specific difficulties, however, appear thus invalidating most of those proposals. The best option requires the use of kaon regeneration effects and could lead to a successful test if moderate kaon detection efficiencies are achieved.

  1. Quantum Tomography in Neutral Meson and Antimeson Systems

    hep-ph 2025-07 conditional novelty 6.0 of 10

    The complete flavor density matrix of a neutral meson-antimeson pair can be reconstructed from time-dependent semileptonic decay rates, with B_s^0 and K^0 the most favorable systems.

  2. Colliders are Testing neither Locality via Bell's Inequality nor Entanglement versus Non-Entanglement

    hep-ph 2025-07 conditional novelty 4.0 of 10

    Collider measurements of final-state momenta alone cannot certify Bell nonlocality or entanglement, because the measured angular distribution is itself a local hidden variable model.
