Energetic γ-rays from TeV scale dark matter annihilation resummed

The annihilation cross section of TeV scale dark matter particles χ0 with electroweak charges into photons is affected by large quantum corrections due to Sudakov logarithms and the Sommerfeld effect. We calculate the semi-inclusive photon energy spectrum in χ0χ0→γ+X in the vicinity of the maximal p...
