T and CPT SYMMETRIES in ENTANGLED NEUTRAL MESON SYSTEMS
Abstract. Genuine tests of an asymmetry under T and/or CPT transformations imply the interchange between in-states and out-states. I explain a methodology to perform modelindependent separate measurements of the three CP, T and CPT symmetry violations for transitions involving the decay of the neutral meson systems in Band Φ-factories. It makes use of the quantum-mechanical entanglement only, f...
متن کاملCpt Violation , Strings , and Neutral - Meson Systems
Symmetry under the discrete transformation CPT is a general theoretical condition holding for local relativistic field theories of point particles [1]-[7]. This symmetry has been investigated experimentally under different circumstances and to a high degree of precision [8]. The broad theoretical validity of CPT symmetry for particles and the availability of high-precision tests makes CPT viola...
متن کاملCpt and Lorentz Violation in Neutral-meson Oscillations
Local relativistic quantum field theories, including the standard model of particle physics, are known to be invariant under Lorentz and CPT transformations. This symmetry is consistent with the results of numerous sensitive laboratory tests. Although no definitive violation has been discovered to date, there are many reasons to undertake careful theoretical studies of possible mechanisms and d...
متن کاملSignals for CPT and Lorentz Violation in Neutral-Meson Oscillations
Experimental signals for indirect CPT violation in the neutral-meson systems are studied in the context of a general CPTand Lorentz-violating standard-model extension. In this explicit theory, some CPT observables depend on the meson momentum and exhibit diurnal variations. The consequences for CPT tests vary significantly with the specific experimental scenario. The wide range of possible effe...
متن کاملDecoherence induced CPT violation and entangled neutral mesons
We discuss two classes of semi-microscopic theoretical models of stochastic space-time foam in quantum gravity and the associated effects on entangled states of neutral mesons, signalling an intrinsic breakdown of CPT invariance. One class of models deals with a specific model of foam, initially constructed in the context of non-critical (Liouville) string theory, but viewed here in the more ge...
