Abstract
Neutral kaon pairs produced in @f decays offer a unique possibility to perform fundamental tests of discrete symmetries. Among the most recent results obtained by the KLOE experiment at DA@FNE, the Frascati @f-factory, there is the new best limit on the branching ratio of the CP-violating decay K_S->3@p^0, BR<2.6x10^-^8 at 90% C.L.. The search for possible violations of the CPT symmetry and Lorentz invariance in the context of the Standard-Model Extension (SME) is also described the new analysis approach fully exploits quantum interferometry in @f->K_SK_L->@p^+@p^-, @p^+@p^- decays. Finally the status and perspectives of the new data taking campaign with the KLOE-2 experiment at the upgraded DA@FNE machine are briefly reviewed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
