Abstract content
The Search for Antimatter in the galactic cosmic radiation is one of the main scientific objectives of the BESS-Program. A flatter antiproton spectrum below the secondary production peak at 1 GeV would suggest novel antiproton source, such as evaporating black-holes or decaying super-symmetric particles. The BESS-Polar experiment is designed as a highly transparent magnetic rigidity spectrometer that can precisely detect antiprotons down to energies of 0.1 GeV where a potential excess of antiprotons over the secondary production might be more apparent. The BESS-Polar instrument had its first successful balloon flight in December 2004, from McMurdo Station in Antarctica. During the 8.5-day long flight 900 million events where recorded. In this paper, we discuss the spectra of antiproton and proton as well as the search for antihelium.
