BaBar Tests of Lorentz and CPT Symmetry

Tests of CPT and T symmetries and a limit on the difference between the decay rates of the two mass eigenstates in B0-mesons oscillations are reported. The reconstructed B decays, comprising both CP and flavor eigenstates, are obtained from Υ(4S) → B(bar B) decays collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. Sensitivity projections for sidereal time modulation of the CPT-violating parameter based on an explicit and general CPT-breaking standard model extension are also discussed
