Abstract
The observables used in the K-system to characterize T and CPT violation are
no longer useful for the Bd-system, since the width difference between the
physical states is vanishingly small. We show that only Im(epsilon) and
Re(delta) can survive if Delta Gamma=0, and build alternative CP-odd, CPT-odd,
T-odd and temporal asymmetries for the (B_CP -> B0, B0bar) transitions. These
quantities enable us to test T and CPT invariances of the effective Hamiltonian
for the B-system. The method needs the CP eigenstates B_CP, which can be tagged
unambiguously to order lambda^3 from the entangled states of a B-factory.
