Search for dark matter annihilation signals from dwarf spheroidal galaxies with H.E.S.S. (15'+5')
 
Dwarf spheroidal galaxies are among the most promising targets for the indirect
search of WIMP annihilation signal with very high energy (VHE) gamma-ray 
experiments.
The absence of standard astrophysical sources in the dwarf spheroidal galaxies
considerably reduces the contamination of a possible exotic signal.
The H.E.S.S. array of 4 Imaging Atmospheric Cherenkov Telescopes, situated in 
the
Southern Hemisphere, have already observed some of these objects for energies 
above
few hundred GeV. After applying selection criteria, 18 hours of data are 
presently
available for the analysis of the Sagittarius dwarf galaxy. Results on the
velocity-weighted annihilation cross sections for Sagittarius dwarf are given in 
the
frameworks of Supersymmetric and Kaluza-Klein models and plausible dark 
matter halo
models are used.
