Gamma-ray constraints on dark-matter annihilation to electroweak gauge and Higgs bosons
Dark-matter annihilation into electroweak gauge and Higgs bosons results in $\gamma$-ray emission. We use observational upper limits on the fluxes of both line and continuum $\gamma$-rays from the Milky Way Galactic Center and from Milky Way dwarf companion galaxies to set exclusion limits on allowed dark-matter masses. (Generally, Galactic Center …
