Hunting for heavy winos in the Galactic Center
Published 2018“…We emphasize the impact of including the non-trivial spectral shape, and we carefully treat the region of interest, presenting results for choices between 1° and 4° from the Galactic Center. Projected limits for wino masses from 1–70 TeV are interpreted as a constraint on the wino annihilation rate, or alternatively as the minimum core size required such that the wino is not excluded. …”
