Neutron beam test of CsI crystal for dark matter search

We have studied the response of Tl-doped and Na-doped CsI crystals to nuclear recoils and γ’s below 10 keV. The response of CsI crystals to nuclear recoil was studied with mono-energetic neutrons produced by the H(p,n)He reaction. This was compared to the response to Compton electrons scattered by 662 keV γ-ray. Pulse shape discrimination between the response to these γ’s and nuclear recoils wa...

Search for Dark Matter

We know a lot about dark matter (DM). First of all we know it exists: modified gravity models cannot explain the spatial segregation between the regions where most of the mass is and where most of the visible matter is in the “bullet cluster” [1] (a cluster formed by two colliding galaxies). In this cluster, the regions where most of the gravitational potential is (as mapped though gravitationa...

Indirect Search for Dark Matter

Possible dark matter candidates are reviewed as well as indirect search methods based on annihilation or decay channels of these particles. Neutralino is presently the best particle candidate and its annihilation produces high energy neutrinos, antiprotons, positrons and γ -rays. To date, only upper limits on neutrino fluxes from the center of the Earth or the Sun, were established by different...

Search for Dark Matter in the Sky

Can we learn about New Physics with astronomical and astro-particle data? Since its launch in 2008, the Large Area Telescope, onboard of the Fermi Gamma-ray Space Telescope, has detected the largest amount of gamma rays in the 20MeV 300GeV energy range and electrons + positrons in the 7 GeV1 TeV range. These impressive statistics allow one to perform a very sensitive indirect experimental searc...

The Search for Dark Matter Axions

Axions solve the Strong CP Problem and are a cold dark matter candidate. The combined constraints from accelerator searches, stellar evolution limits and cosmology suggest that the axion mass is in the range 3 · 10 > ma > 10 −6 eV. The lower bound can, however, be relaxed in a number of ways. I discuss the constraint on axion models from the absence of isocurvature perturbations. Dark matter ax...
