Tests of CPT Symmetry in B~0-{-under letter B}~0 Mixing and in B~O → c{-under letter c}K~0 Decays

摘要

On behalf of the BABAR Collaboration Using the time dependences for the decays {formula}, we determine the three CPT-sensitive parameters Re (z) and Im (z) in{formula} mixing and {formula}decays. We find Im (z)= 0.010±0.030±0.013, Re (z)= -0.065±0.028±0.014, and | A/A|= 0.999±0.023±0.017, in agreement with CPT symmetry. The Re (z) result provides a limit on one component of Lorentz-symmetry violation.
