Dark Matter Search with the CALET Detector on-board ISS
Abstract
We are proposing the CALET CALorimetric Electron Telescope mission for the observation high energy electrons and gamma-rays at the Exposed Facility of the Japanese Experiment Module on the International Space Station The CALET has a capability to detect the gamma-rays in 20 MeV sim a few TeV and the electrons in 1 GeV sim 10 TeV with an excellent energy-resolution 2 at 100 GeV and better at higher energies a good angular resolution 0 06 degree at 100 GeV and a sufficient proton-rejection power nearly 10 6 for electrons up to 10 TeV The geometrical factor is nearly 1 m 2 sr and three year observation is expected Therefore the CALET enables us to detect gamma-ray lines in the GeV sim TeV region expected from WIMP dark matter By a very precise and high statistics measurement of the electrons plus positrons the CALET might find a distinctive feature caused from the KK dark matter in the Galactic halo As a result the CALET has a unique capability to search for WIMP dark matter by the hybrid observation of electrons and gamma-rays
