This provides a dynamical, rather than a kinematical, description of photon polarization correlations as stemming from the ever precise and realistic QED theory. Such computations may be relevant to recent and future experiments involved in testing Bell-like inequalities as described.16 pages, PDF, misprints correctedQuantum PhysicsJoint Probabilities of Photon polarization Correlations in $e^{+}e^{-}$ Annihilationtext
