Sommerfeld-corrected relic abundance of wino dark matter with NLO electroweak potentials
Martin Beneke, Robert Szafron, K. Urban
Abstract
A bstract 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 including the Sommerfeld effect at the next-to-leading order (NLO).
