The light gaugino (bino or wino) scenario - Standard MSSM variant:

The Lagangian of light Higgsino interactions with photons and vector bosons is
+ +
It is unlikely since: Obtained by fine tuning to theW-boson mass It is contrary to well known experimental constraints

Astrophysical methods: • Direct detection experiments – registration of nuclear recoils generated in the processes of elastic WIMP’s scattering off the matter nuclei National Underground Scientific and Engineering Laboratory (NUSEL), USA
The elastic scattering neutralino-nucleon cross section is spin-dependent only. -- 1 ton of liquid xenon Detector Local DM density Separated neutralino flux Neutralino-xenon cross section Estimation gives reliable signal ! Planned background
Exotic effect of neutralino recharging on nucleons The threshold is
2) Satellite experiments for detection of neutralino annihilation products from the galactic halo. - channel - channels
Characteristic photon energies -- are available for GLAST
We obtained the maximal flux for NFW (Navarro, Frenk and White) clump density profile This flux is comparable with maximal limit of GLAST sensitivity
