In this work we study the T, CP and CPT symmetries in the B-meson system. Our analysis and results are addressed to the case of correlated mesons in the B-factories. In the first set of theory and results we investigate the consequences of these discrete symmetries in the B-mixing and interference between mixing and decay. With the help of the CP-tag we compute all possible intensities and asymmetries which concern flavour-specific and CP Golden Plate decays. Our proposed observables are a new self-consistency check for the Standard Model, as well as a new exploration for the traces of the discrete symmetries in the B-system. In the second set of results we study CPT violation in the initial state of the B-factories through the loss of indistinguishability of B0 and B0. We show that, if the consequence of Bose statistic is relaxed, then the equal-sign dilepton events are considerably modified. We analyze the demise of flavour tagging and we also prove that the equal-sign charge asymmetry, Asl, is an optimal observable where to look for this new CPT violation effect. The detailed study of this asymmetry allows us to predict different behaviours according to the possible values of the CPT violating parameter \w. We conclude that the best observable where to find traces of this novel kind of CPT violation is the analysis of Asl at small \Dt's. We use existing data on Asl to put the first limits on \w.
