Dark Matter and Neutrinos

• Three unsolved problems in Astroparticle Physics and Cosmology:

• Cosmic Ray Origin

  • <1014eV Supernovae shock remnants
  • >1016eV Unknown origin:

    • PeV gamma rays as tracers: inconclusive
    • EeV cosmic rays as tracers: Auger project

• Neutrino Mass

  • Atmospheric problem
  • Solar problem
  • Solution: neutrino mass -> oscillations

    • Absolute mass value
    • 10eV: potential dark matter
    • 10-2eV: not cosmologically significant

• Dark Matter

  • 90% of the Universe!

    • WIMPs:neutralino -> PP input from supersymmetry
    • MACHOs: black holes / dead stars
