Search for antimatter and dark matter, precision studies of the cosmic rays fluxes on the international space station. AMS experiment. Results of four year exposure


Massachusetts Institute of Technology, Cambridge, USA

The results of the cosmic rays studies, obtained in the AMS experiment during 2011—2015 on the International Space Station, are given. The energy spectra of electrons and positrons at Tev-energies as well as precision measurements of fluxes were performed. The growth with energy of the positron fraction has been observed. Also the proton and Helium spectra have been obtained. A review of theoretical models with possible explanations of the observed phenomena is presented.
