Using the eight time dependences e[superscript -Γt](1+C[subscript i]cosΔmt+S[subscript i]sinΔmt) for the decays Υ(4S)→B[superscript 0][bar over B][superscript 0]→f[subscript j]f[subscript k], with the decay into a flavor-specific state f[subscript j]=ℓ[superscript ±]X before or after the decay into a CP eigenstate f[subscript k]=c[bar over c]K[subscript S,L], as measured by the BABAR experiment, we determine the three CPT-sensitive parameters Re(z) and Im(z) in B[superscript 0]-[bar over B][superscript 0] mixing and |A/[bar over A]| in B[superscript 0]→c[bar over c]K[superscript 0] decays. We find Im(z)=0.010±0.030±0.013, Re(z)=-0.065±0.028±0.014, and |[bar over A]/A|=0.999±0.023±0.017, in agreement with CPT symmetry.
