Description

The region surrounding the Galactic Center (GC) is one of the richest and most promising targets for the indirect detection of dark matter. Using large-zenith-angle KM2A data, we search for annihilating dark matter in the mass range 10 TeV–1 EeV. We derive the strongest constraints to date on the velocity-weighted annihilation cross section around 100 TeV, improving existing limits from dwarf spheroidal galaxy studies by about an order of magnitude.
