  • 摘要:In 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 avour specic decays and we nd a considerable modication in the Dt-dependence of the equal-sign dilepton charge asymmetry, Asl . 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 Asl , we put the rst limits on w.
