We derive new Bell’s inequalities for entangled K0K̅ 0 pairs. This requires (1) mutually exclusive setups allowing either K0 vs K̅ 0 or KS vs KL detection and (2) the use of kaon regenerators. The inequalities turn out to be significantly violated by quantum mechanics, resulting in interesting tests of local realism at φ factories and pp̅ machines.
