eta Physics and phi Radiative Decays at Kloe
Here we present KLOE results on the phi meson decays in pi0 pi0 gamma, pi+ pi- gamma and eta pi0 gamma, the measurement of the ratio Br(phi to eta' gamma)/Br(phi to eta gamma) with the estimate of the eta' gluonium content and the measurement of the eta mass.

Indirect dark matter search with AMS-02
The Alpha Magnetic Spectrometer (AMS), to be installed on the International Space Station, will provide data on cosmic radiations in the energy range from 0.5 GeV to 3 TeV. The main physics goals are the anti-matter and the dark matter searches. Observations and cosmology indicate that the Universe may include a large amount of unknown Dark Matter. It should be composed of non baryonic Weakly Interacting Massive Particles (WIMP). In R-parity conserving models a good WIMP candidate is the lightest SUSY particle. AMS offers a unique opportunity to study simultaneously SUSY dark matter in three decay channels resulting from the neutralino annihilation: e+, antiproton and gamma. Either in the SUSY frame and in alternative scenarios (like extra-dimensions) the expected flux sensitivities as a function of energy in 3 year exposure for the e+/e- ratio, gamma and antiproton yields are presented.

Latest Results from Dafne
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.
