Due to its proximity the GC yields the largest expected flux from particle dark matter annihilation and thus the lowest exclusion limit. Nevertheless, this minimum measurable flux is more than one order of magnitude above the highest fluxes predicted by SUSY models (full circles).

For this profile also the flux measured by the HESS experiment is far above the theoretical expectation. In the extreme case of adiabatic compression some models might be in reach of the observations.
