The existence of a dark matter (DM) model with a rich dark sector could be the reason why WIMP DM has evaded its detection so far. For instance, colored co-annihilation naturally leads to the prediction of heavier DM masses. Moreover, non-perturbative effects such as Sommerfeld corrections and bound state formation must be considered to accurately predict the DM relic abundance. In the context...
Simplified t-channel dark matter models serve as a versatile and well-motivated framework for rich
dark sectors that are widely studied by ongoing experimental and theoretical efforts. In this work,
we investigate the impact of non-perturbative effects on the dark matter relic abundance for two
representative models of this kind of models, focusing on regions of parameter space where...
The nature of dark matter in our Universe remains one of the most compelling inquiries in fundamental physics today. While weakly interacting massive particles (WIMPs) have been the primary candidates for dark matter in the past decades, alternative explanations have gained more and more attention due to a growing number of null-results in experimental WIMP searches. Here, we go beyond the...
