2. Characteristic scales of the MSSM

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

5. -- --

6. The Lagangian of light Higgsino interactions with
photons and vector bosons is

8. + +

13. It is unlikely since: Obtained by fine tuning to the W-boson mass
It is contrary to well known experimental constraints

14. -- --

17. 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

18. The elastic scattering neutralino-nucleon cross section is spin-dependent only.
Detector
-- 1 ton of liquid xenon
Local DM density
Separated neutralino flux
Neutralino-xenon cross section
Estimation gives
reliable signal !
Planned background

19. Exotic effect of neutralino recharging on nucleons
The threshold is

20. 2) Satellite experiments for detection of neutralino
annihilation products from the galactic halo.

- channels

21. Characteristic photon energies
-- are available for GLAST

23. Diffuse gamma ray spectrum

25. We obtained the maximal flux
for NFW (Navarro, Frenk and White) clump density profile
This flux is comparable with maximal limit of GLAST sensitivity
