Dark Matter Direct Searches
Cosmology and astrophysics indicate that our Universe contains a considerable amount of `dark matter’ that is associated with an unknown elementary particle. LIPSS experiment at Jefferson Lab used a high average-power laser beam from a Free Electron Laser to probe for two-photon coupling of such particles using a `light shining through a wall’ technique. Non-observation of a new scalar boson...

I discuss the status of data from direct detection experiments including DAMA, CDMS, CoGeNT and others, with a particular emphasis on the WIMP mass region around 10 GeV. The possibility to explain these data in terms of spin-independent or spin-dependent elastic or inelastic scattering is discussed.

Dark Matter Indirect Searches
Directional detection of galactic Dark Matter is a promising search strategy for discriminating genuine WIMP events from background ones. Indeed, due to the Earth rotation around the Galactic center through the dark matter halo, the WIMP-induced recoil distribution should be pointing toward the Cygnus Constellation. I will present a comprehensive statistical method allowing to recover...

One of the most promising particle candidates for DM is the supersymmetric neutralino or more generally a weakly interacting massive particle (WIMP). The expected interaction rate of WIMPs in direct search experiments is below 0.01 events / (kg day), thus rising up the importance of having a detailed understanding of potential background. Ambient and muon-induced neutrons constitute a...
