摘要：
Direct tests of T, CP, CPT symmetries in transitions processes of neutral kaons are briefly reviewed. The exchange of in and out states required for a genuine test involving time-reversal is implemented exploiting the entanglement of K-0(K) over bar (0) pairs produced at a phi-factory. A data sample collected by the KLOE experiment at DA Phi NE corresponding to an integrated luminosity of about 1.7 fb(-1) is analysed to study the phi -> KSKL -> pi(+)pi- pi e nu and phi -> KSKL -> pi e nu 3 pi(0) processes, and to perform the first direct tests of T and CPT symmetries in kaon transitions with a precision of few percent, and to observe CP violation with this novel method.
