چکیده انگلیسی
The search of dark matter signals in space has considerably progressed in the recent years by the PAMELA space mission and the long duration flight balloon-borne BESS Polar experiments. Interesting and intriguing results have been obtained by PAMELA in the positron to electron fraction, theoretically interpreted as contributions from dark matter annihilation or nearby pulsars. More standard explanations are not excluded. The results on the antiproton flux and the antiproton-to-proton ratio obtained by PAMELA and BESS are in agreement with secondary production mechanisms. AMS-02 operating outside the ISS since May 2011 should clarify the positron fraction puzzle and open new windows in the cosmic-rays study.
