Past-Future Interference in $\Phi$-Decays into Entangled Kaon Pairs

Abstract

Quantum interference effects between past and future events (neutral kaon transitions, including CP violating decays) are discussed for entangled kaon pairs produced through $\phi \to K^0 \bar{K^0}$ in $\phi$-factories. Contrasting with the exciting conclusions of other recent analyses, we predict the inexistence of such an observable effect.
