Excited bound states and their role in dark matter production

Tobias Binder, Mathias Garny, Jan Heisig +2

We explore the impact of highly excited bound states on the evolution of number densities of new physics particles, specifically dark matter, in the early Universe. Focusing on dip…

Sommerfeld enhancement of resonant dark matter annihilation

Martin Beneke, Stefan Lederer, Kai Urban

The dark matter annihilation cross section can be amplified by orders of magnitude if the annihilation occurs into a narrow resonance, or if the dark-matter particles experience a…

Matching resummed endpoint and continuum -ray spectra from dark-matter annihilation

Martin Beneke, Kai Urban, Martin Vollmann

For the minimal wino and Higgsino benchmark models we provide accurate energy spectra of high-energy photons from TeV scale dark-matter annihilation by merging electrow…

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…
