摘要：
The presentation reviews the results which have been obtained with the BABAR detector at the e(+)e(-) storage ring PEP-II at SLAC between 2004 and 2016 on T and CPT symmetry in B-0-(B) over bar (0) mixing and in the decay amplitudes of (B) over bar (0) -> c (c) over barK(0) decays. All results are based on the measured time dependence of two-decay events from entangled B-B pairs produced in decays of gamma(4S) mesons. Neither T nor CPT violation have been observed in B-0-(B) over bar (0) mixing, also no CPT violation in the B-0 -> c (c) over barK(0) decay amplitudes.
