Abstract

Using the eight time dependences e−Γtð1þCi cosΔmtþSi sinΔmtÞ for the decays Υð4SÞ→B0B ̄ 0 →fjfk, with the decay into a flavor-specific state fj 1⁄4 l`X before or after the decay into a CP eigenstate fk 1⁄4 cc ̄KS;L, as measured by the BABAR experiment, we determine the three CPT-sensitive parameters ReðzÞandImðzÞinB0-B ̄0 mixingandjA ̄=AjinB0 →cc ̄K0 decays.WefindImðzÞ1⁄40.010`0.030`0.013, ReðzÞ1⁄4−0.065`0.028`0.014, and jA ̄=Aj1⁄40.999`0.023`0.017, in agreement with CPT symmetry.
