Abstract	The quest to discover the nature of dark matter continues to drive many of the experimental and observational frontiers in particle physics, astronomy, and cosmology. While there are no definitive signatures to date, there exists a rich ecosystem of experiments searching for signals for a broad class of dark matter models, at different epochs of cosmic history, and through a variety of processes with different characteristic energy scales. Given the multitude of candidates and search strategies, effective field theory has been an important tool for parametrizing the possible interactions between dark matter and Standard Model probes, for quantifying and improving model-independent uncertainties, and for robust estimation of detection rates in the presence of large perturbative corrections. This white paper summarizes a wide range of effective field theory applications for connecting dark matter theories to experiments.

$(Left) WIMP-proton scattering cross section as a function of the WIMP mass for a Majorana triplet. For $M \gtrsim 700 {\rm GeV}$, the prediction is given by the universal $M \to \infty$ limit. The red band represents perturbative and hadronic input uncertainties, and includes sample model-dependent $1/M$ corrections. The orange band estimates the impact of $1/M^2$ corrections. Figure taken from Ref.~\cite{Chen:2018uqz}. (Right) The impact of perturbative QCD corrections on the universal cross section is illustrated as a function of the Higgs mass. Bands represent predictions including higher-order contributions (as labeled) to the running and matching calculations below the weak-scale. Figure taken from Ref.~\cite{Hill:2013hoa}.$ $Results reproduced from Ref.~\cite{Rinchiuso:2020skh} showing the sensitivity of CTA to Higgsino (left) and wino (right) DM annihilation in the galactic center. For the Higgsino, the result suggest that CTA could be sensitive to the cross-section predicted at the thermal mass $\sim$1\,TeV. However, the theory prediction does not include the effects of the EFT of Heavy DM, which could easily shift the result in either direction by a factor of few, and provides a clear motivation for this work. For the wino, one sees that even with extremely conservative assumptions about the DM content of the inner galaxy, corresponding to a very large core size, the predicted cross section at the thermal mass of $\sim$3\,TeV will be excluded ({\it cf.} at present this is not excluded by HESS~\cite{Rinchiuso:2018ajn}). We refer to Ref.~\cite{Rinchiuso:2020skh} for additional details.$ $Results reproduced from Ref.~\cite{Rinchiuso:2020skh} showing the sensitivity of CTA to Higgsino (left) and wino (right) DM annihilation in the galactic center.
