dc.description.abstract In this paper we discuss experimental consequences of a novel kind of CPT violation which would manifest itself in the symmetry of the entangled initial state of B-0 and (B) over bar (0) through their loss of indistinguishability. The 'wrong' symmetry component is proportional to omega. We focus our theoretical study on the Delta t-dependence of observables concerning equal-sign dilepton events for which the intensity vanishes at Delta t = 0 in absence of omega. We find that the charge asymmetry, A(sl), acquires a Delta t-dependence linear in !, whose relative importance appears on specific regions of time still unexplored. We also do a statistical analysis for the measurements here proposed and find a high sensitivity to this new CPT-violating effect in this charge asymmetry. We obtain the first limits on the omega-effect by re-analyzing existing data on the Asl asymmetry.
