Here, using the eight time dependences e-Γt(1 + Ci cos Δmt + Si sin Δmt) for the decays Y(4S)→B0$$\bar{B}$$0→fjfk, with the decay into a flavor-specific state fj= ± X before or after the decay into a CP eigenstate fk=c$$\bar{c}$$ KS,L, as measured by the BABAR experiment, we determine the three CPT-sensitive parameters Re(z) and Im(z) in B0$$\bar{B}$$0 mixing and |$$\bar{A}$$/A| in B0→c$$\bar{c}$$ K0 decays. We find Im(z) = 0.010 ± 0.030 ± 0.013, Re(z) = -0.065 ± 0.028 ± 0.014, and |$$\bar{A}$$/A|=0.999±0.023±0.01, in agreement with CPT symmetry.
