The present and future of particle dark matter

Dark matter physics has changed dramatically in the last ten years. Sustained progress in both collider searches and laboratory direct detection experiments has reshaped the viable parameter space for particle dark matter: the WIMP paradigm that guided theoretical and experimental progress for decades has been increasingly constrained, and as a result, a huge variety of alternative candidates are ascendant. New experimental tools and approaches have opened new frontiers, from light dark matter below the MeV scale to ultraheavy particles far above the weak scale, and theoretical developments have supplied a wide range of exciting targets for each of these regimes. I will give a broad overview of the current state of particle dark matter physics, with particular focus on recent and near-future experimental results that are defining the direction of the field for the coming years. In terrestrial laboratories, the methods that have been so effective in probing WIMP parameter space are now being adapted for the next generation of searches. At the same time, a huge range of new opportunities have been identified in astrophysical and cosmological data. I will point out some of the most interesting targets for these tools, and highlight promising areas for theoretical and technological developments to substantially advance dark matter science in the coming decade.
