Bell-inequalities for Entangled Neutral Kaons

Abstract

We extend the use of Bell-inequalities to $\Phi \to K^0\overline{K^0}$ decays by exploiting analogies and differences to the well-known and experimentally verified singlet-spin case. Contrasting with other analyses, our Bell-inequalities are violated by quantum mechanics and can strictly be derived from local realistic theories. In principle, quantum mechanics could then be tested using unstable, oscillating states governed by a CP-violating Hamiltonian.
