Using time-dependent indirect CP asymmetries to measure T and CPT violation in B0–B¯0 mixing

Quantum field theory, which is the basis for all of particle physics, requires that all processes respect CPT invariance. It is therefore of paramount importance to test the validity of CPT conservation. In this Letter, we show that the time-dependent, indirect CP asymmetries involving B decays to a...

Summary:Quantum field theory, which is the basis for all of particle physics, requires that all processes respect CPT invariance. It is therefore of paramount importance to test the validity of CPT conservation. In this Letter, we show that the time-dependent, indirect CP asymmetries involving B decays to a CP eigenstate contain enough information to measure T and CPT violation in B0–B¯0 mixing, in addition to the standard CP-violating weak phases. Entangled B0B¯0 states are not required (so that this analysis can be carried out at LHCb, as well as at the B factories), penguin pollution need not be neglected, and the measurements can be made using Bd0 or Bs0 mesons.
