Description
The existence of a dark matter model with a rich dark sector could be the reason why WIMP dark matter has evaded its detection so far. For example, colored co-annihilation naturally leads to the prediction of heavier dark matter masses. Importantly, in such a scenario the Sommerfeld effect and bound state formation must be considered in order to accurately predict relic abundance. We use the widely studied t-channel simplified model with a colored mediator to demonstrate the importance of considering these non-perturbative effects and discuss its impact on constraints on the paramater space of the model from the LHC and direct detection experiments.
