Remarks on Causality in Relativistic Quantum Field Theory



It is shown that the correlations predicted by relativistic quantum field theory in locally normal states between projections in local von Neumann algebras \({\cal A}\)(V1),\({\cal A}\)(V2) associated with spacelike separated spacetime regions V1,V2 have a (Reichenbachian) common cause located in the union of the backward light cones of V1 and V2. Further comments on causality and independence in quantum field theory are made.
