Resonant s-channel dark matter annihilation at NLO
Abstract Studies of dark matter annihilation through an s-channel resonance are often based on recipes such as a narrow width approximation or real intermediate state subtraction. We review a recipe-free formalism that can be implemented at the NLO level in the full theory, and ensures the cancellat...
