The omega effect as a discriminant for spacetime foam

摘要: If there is CPT violation, the nature of entanglement for neutral meson pairs produced in factories may, on general grounds, be affected. The new form omega effect. Gravitational decoherence, due to spacetime foam, may one route deviations from invariance. Two models foam are considered. One, based non-critical string theory, able produce correlations a natural way. other, paradigm thermal-like baths, shown surprisingly resistant producing effect even exercising total freedom choice state bath.
