Precise yield of high-energy photons from Higgsino dark matter annihilation
Abstract The impact of electroweak Sudakov logarithms on the endpoint of the photon spectrum for wino dark matter annihilation was studied intensively over the last several years. In this work, we extend these results to Higgsino dark matter χ 1 0 $$ {\chi}_1^0 $$ . We achieve NLL′ resummation accur...
