Abstract

Using the eight time dependences e-Γt(1+CicosΔmt+SisinΔmt) for the decays ϒ(4S)→B0B 0→fjfk, with the decay into a flavor-specific state fj=±X before or after the decay into a CP eigenstate fk=cc KS,L, as measured by the BABAR experiment, we determine the three CPT-sensitive parameters Re(z) and Im(z) in B0-B 0 mixing and |Ā/A| in B0→cc K0 decays. We find Im(z)=0.010±0.030±0.013, Re(z)=-0.065±0.028±0.014, and |Ā/A|=0.999±0.023±0.017, in agreement with CPT symmetry.
