AbstractWe discuss the demise of flavour tagging due to the loss of the particle–antiparticle identity of neutral B-mesons in the Einstein–Podolsky–Rosen correlated states. Such a situation occurs in cases where the CPT operator is ill-defined, as happens, for example, in quantum gravity models with induced decoherence in the matter sector. The time evolution of the perturbed B0–B¯0 initial state, as produced in B-factories, is sufficient to generate new two-body states. For flavour specific decays at equal times, we discuss two definite tests of the two body entanglement: (i) search for the would-be forbidden B0B0 and B¯0B¯0 states; (ii) deviations from the indistinguishable probability between the permuted states B¯0B0 and B0B¯0.
