One of the on-board detectors, the Mini-Calorimeter (MCAL), was also designed to work as all sky transient monitor in the energy range 0.33-100 MeV. Though

The lightest supersymmetric particle (LSP), is a reasonable, and perhaps the most promising, candidate for the dark matter of the universe. The neutralino annihilation into the gamma gamma and gamma Z final states can give rise to gamma rays with unique energies. GLAST can search for gamma-ray lines in the mass above 30 GeV thanks to its excellent energy resolution. The portion of the Supersymmetric Models parameters space that can be explored will be examined.

We investigate whether the spectral features of this source are compatible with the γ-ray flux induced by pair annihilations of dark matter weakly interacting massive particles (WIMPs). We show that the discrimination between this interpretation and other viable explanations will be possible with GLAST, the next major γ-ray telescope in space. On the other hand, we also show that if the data will point to an alternative explanation, there will still be the possibility for GLAST to single out a weaker dark matter source at the GC. The talk is entirely based on Cesarini et al. 2003.

Here we present the project of an antarctic flight of a balloonborne apparatus that in principle could be greatly helpful in clarifying the situation before that experiments on space station or satellites provide the high statistics
