33RD INTERNATIONAL COSMIC RAY CONFERENCE, RIO DE JANEIRO 2013 THE ASTROPARTICLE PHYSICS CONFERENCE Dark Matter Search Perspectives with GAMMA-400

Abstract: GAMMA-400 is a future high-energy γ-ray telescope, designed to measure the fluxes of γ-rays and cosmic-ray electrons + positrons, which can be produced by annihilation or decay of dark matter particles, and to survey the celestial sphere in order to study point and extended sources of γ-rays, measure energy spectra of Galactic and extragalactic diffuse γ-ray emission, γ-ray bursts, and γ-ray emission from the Sun. GAMMA-400 covers the energy range from 100 MeV to ∼3000 GeV. Its angular resolution is ∼ 0.01◦(Eγ> 100 GeV), and the energy resolution ∼ 1 % (Eγ> 10 GeV). GAMMA-400 is planned to be launched on the Russian space platform Navigator in 2019. The GAMMA-400 perspectives in the search for dark matter in various scenarios are presented in this pape
