Weakly interacting massive particles (WIMPs) are among the most discussed and promising candidates for dark matter to date. If these WIMPs have TeV-scale masses, the hierarchy between the dark matter mass and the electroweak scale induces large electroweak corrections which require resummation. In this talk, I will discuss how the inclusion of non-relativistic potentials (leading to the so-called Sommerfeld enhancement) up to next-to-leading order modifies the predicted dark matter relic abundance and indirect detection signal. Furthermore, I will also outline how the resummation of Sudakov logarithms further reshapes the gamma-ray signal in indirect detection experiments.
