  Relativistic EPR-type experiments for photons in the background of reducible
representation algebras are discussed. A model for the four Bell states, such
that maintains maximally correlated in two bases: linear and circular in all
reference frames is developed. Relativistic correlation functions are derived
for two cases: when the detectors are transformed under Lorentz transformation
in such a way that they still remain in the same reference frame and when just
one of the detectors is transformed.
