Abstract: We focus on two aspects of CPT invariance in neutral meson-antimeson (M-0 (M) over bar (0)> mixing: (1) tests of CPT invariance, using only the property of "lack of vacuum regeneration", which occurs as a part of the well-known Lee-Oehme-Yang (LOY) theory; (2) methods for extracting the CPT-violating mixing parameter theta through explicit calculations by fully using the LOY-type theory. In the latter context, we demonstrate the importance of the C-even \M-0 (M) over bar (0)> state. In particular, by measuring the time dependence of opposite-sign dilepton events arising from decays of the C-even and C-odd \M-0 (M) over bar (0)> states, theta may be disentangled from the parameters lambda(+) and lambda(-) characterizing violations of the DeltaF = DeltaQ rule. Furthermore, these two parameters may also be determined. The same is true if one uses like-sign dilepton events arising from only the C-even \M-0 (M) over bar (0)>) state.
