NLO electroweak potentials for minimal dark matter and beyond
Kai Urban
We calculate the one-loop correction to the static potential induced by , and -exchange at tree-level for arbitrary heavy standard model multiplets. We find that the resu…
Sommerfeld-corrected relic abundance of wino dark matter with NLO electroweak potentials
Martin Beneke, Robert Szafron, Kai Urban
Extending previous work, we calculate the electroweak potentials for all co-annihilation channels of wino dark matter at the one-loop order and obtain the wino relic abundance incl…
Precise yield of high-energy photons from Higgsino dark matter annihilation
Martin Beneke, Caspar Hasner, Kai Urban +1
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 w…
Wino potential and Sommerfeld effect at NLO
Martin Beneke, Robert Szafron, Kai Urban
We calculate the SU(2)U(1) electroweak static potential between a fermionic triplet in the broken phase of the Standard Model in the one-loop order (NLO). The one-loop corr…
Resummed photon spectrum from dark matter annihilation for intermediate and narrow energy resolution
M. Beneke, A. Broggio, C. Hasner +2
The annihilation cross section of weakly interacting TeV scale dark matter particles into photons is affected by large quantum corrections due to electroweak Sudakov logarith…
