CP, T and CPT versus temporal asymmetries for entangled states of the Bd-system

The observables used in the K-system to characterize T and CPT violation are no longer useful for the B-d-system, since the width difference Delta Gamma 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+/- --> B-0, (B)over bar(0) 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+/-, which can be tagged unambiguously to O(lambda(3)) from the entangled states of a B-factory. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
