Abstract:
The PAMELA satellite-borne experiment was launched from the Bajkonur launch site
in Kazakhstan on the 15th of June 2006. Measurements of antiprotons and
positrons energy spectra are being performed since July 2006 to search for
exotic sources, such as dark matter particle annihilation. PAMELA is also
looking for primordial antinuclei (antiHe). Other measurements concern light
nuclei energy spectra, the monitoring of the solar activity and the study of the
radiation belts.
Results on antiprotons to protons and positrons to all electrons ratios will be
presented together with preliminary data on the antiprotons and electrons fluxes
and secondary to primary nuclei ratios.
