Using time-dependent indirect CP asymmetries to measure T and CPT violation in B0-Bˉ0 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 CP

factories), penguin pollution need not be neglected, and the measurements can be made even if the
