Description
Although all present tests of CPT invariance confirm this symmetry, impossed by any local quantum field theory with Lorentz invariance, it would be of great interest to observe Time Reversal Violation (TRV) directly in a single experiment, independent of CP, and as a genuine test, implying the interchange between in-states and out-states.
The only theoretical ingredient to perform this test is the quantum-mechanical EPR entanglement, produced after the decay of the Phi or Upsilon(4S) as it is done in the Phi-factories or B-factories, for which the individual state of each neutral meson is not defined before the decay of its orthogonal partner.
The experimental analysis for the measurement of CP, T, and CPT asymmetries as function of the time difference between the first and the second neutral meson decays is discussed, as well as the significance of the expected results in Monte Carlo simulations.
