Violation of CPT and Quantum Mechanics in the K 0 – K̄ 0 System
نویسنده
چکیده
We reconsider the model of quantum mechanics violation in theK0–K̄0 system, due to Ellis, Hagelin, Nanopoulos, and Srednicki, in which CP and CPT -violating signatures arise from the evolution of pure states into mixed states. We present a formalism for computing time-dependent asymmetries in this model and show that present data constrains its parameters significantly. In the future, this model will be put to very stringent tests at a φ factory. We present the theory of these tests and show the relation between particular φ decay correlations and the parameters of quantum mechanics violation.

Binary Systems in Qm and in Qft: Cpt
Quasi-degenerate neutral systems like a (K, K̄) type are investigated in Quantum Field Theory (QFT). A constant mass matrix as the one used in Quantum Mechanics (QM) can only be introduced as a linear approximation to QFT. We study the phenomenological consequences of the differences between the QFT and QM treatments. The role of “spurious” states with zero norm at the poles is emphasized. The K...
متن کاملSymmetry Be Tested With K 0 vs K̄ 0 → π + π − π 0 Decays ?
We show that the CP-violating effect in K vs K̄ → πππ decays differs from that in KL → π π, KL → π π or the semileptonic KL transitions, if there exists CPT violation in K-K̄ mixing. A delicate measurement of this difference in the KTeV experiment and at the φ factory will provide a new test of CPT symmetry in the neutral kaon system. PACS number(s): 11.30. Er, 13.25. Es, 14.40.

متن کاملEmergent CPT violation from the splitting of Fermi points
In a fermionic quantum vacuum, the parameters kμ of a CPT-violating Chern–Simons-like action term induced by CPT-violating parameters bμ of the fermionic sector depend on the universality class of the system. As a concrete example, consider the Dirac Hamiltonian of a fermionic quasiparticle with effective rest energy M and add a term with purely-spacelike CPTviolating parameters bμ = (0,b). Dep...
متن کامل6 An open quantum system approach to EPR correlations in K 0 K̄ 0 system
We find the time evolution of the system of two non-interacting unstable particles, distinguishable as well as identical ones, in arbitrary reference frame having only the Kraus operators governing the evolution of its components in the rest frame. We than calculate in the rigorous way Einstein–Podolsky–Rosen quantum correlation functions for K0K̄0 system in the singlet state taking into account...
متن کاملCP , T AND CPT VERSUS TEMPORAL ASYMMETRIES FOR ENTANGLED STATES OF THE B d - SYSTEM
The observables used in the K-system to characterize T and CPT violation are no longer useful for the B d-system, since the width difference ∆Γ between the physical states is vanishingly small. We show that only Im(ε) and Re(δ) can survive if ∆Γ = 0, and build alternative CP-odd, CPT-odd, T-odd and temporal asymmetries for the B ± → B 0 , ¯ B 0 transitions. These quantities enable us to test T ...
