Abstract

Using the eight time dependences e^(-Delta t)(1+C_i cos(Deltam*t)+S_i sin(Deltam*t)) for the decays Upsilon(4S)-->†’B0B0bar-->fj fk, with the decay into a flavor-specific state fj=l±X before or after the decay into a CP eigenstate fk=ccbarKS,L, as measured by the BABAR experiment, we determine the three CPT-sensitive parameters Re(z) and Im(z) in B0-B0bar mixing and |Abar€/A| in B0-->ccbarK0 decays. We find Im(z)=0.010±0.030±0.013, Re(z)=-0.065±0.028±0.014, and |Abar/A|=0.999±0.023±0.017, in agreement with CPT symmetry.
