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 0 through their loss of indistinguishability. The ``wrong'' symmetry component is proportional to ω. We focus our theoretical study on the Δt-dependence of observables concerning equal-sign dilepton events for which the intensity vanishes at Δt = 0 in absence of ω. We find that the charge asymmetry, Asl, acquires a Δt-dependence linear in ω, 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 ω-effect by re-analyzing existing data on the Asl asymmetry.
