Abstract:

Starting from the time evolution of the C-odd system, we analyze the asymmetries measurable at DANE and their implications on CP violation and on the possible tests of T and CPT symmetries. In particular the ratio can be measured with high precision (up to about for the real part). The CP-, T- and CPT-violating parameters can be explored in semileptonic decays with an accuracy of the order of . The possibility to detect and decays is also discussed.
