Abstract

The Dafne Frascati phi factory has continously improved its performances reaching in 2002 an instantaneous luminosity of 8x10^31 cm-2 s-1. The DEAR experiment, concluded in 2002, has measured the de-excitation of kaonic atoms. The KLOE experiment, still running, has measured several branching ratios for neutral and charged kaons decays, rho, eta, eta', a0 and f0 mesons parameters and, via the radiative return, the e+e- -> pi+pi- cross section. Preliminary and final results are presented.
