Resummed photon spectra from wino and Higgsino dark matter annihilation at NLL' accuracy

This thesis investigates the semi-inclusive photon spectrum for the scattering process χ0 χ0 →γ + X, where χ0 is a heavy, non-relativistic dark matter particle. We focus on the wino and Higgsino dark matter models. The cross section of the aforementioned scattering process is affected by large quantum corrections which are related to the Sommerfeld effect and Sudakov-logarithms. The focus of this work is the resummation of the Sudakov-logarithms.
