Detection of antiparticles with the PAMELA space instrument for antimatter and dark matter research
Piergiorgio Picozza (Università di Roma Tor Vergata)
Seminar Room 3, 15:00
On the 15th of June 2006 the PAMELA satellite-borne experiment
was launched from the Bajkonur launch site in Kazakhstan.
Measurements of antiproton and positron 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 (He). Concomitant goals
are the measurements of light nuclei energy spectra for the study
of the energy dependence of cosmic ray lifetimes in the Galaxy,
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
antiproton and electron fluxes.
