dc.descriptionIn this work we discuss how the loss of particle-antiparticle identity due to CPT violation affects the observables in the decay of two neutral EPR-correlated $B$-mesons. We study this possible new effect in the context of equal-sign flavour specific decays and we find a considerable modification in the $Δt$-dependence of the equal-sign dilepton charge asymmetry, $A_{sl}$. Although the more important changes occur right outside the $\Dt$ region that has been up-to-the-date effectively explored, we show that a deeper experimental research may be able to distinguish a possible existence of this new CPT violating parameter, $\w$. In any case, using the available data for $A_{sl}$, we put the first limits on $\w$.
