Snowmass 2021 Cross Frontier Report: Dark Matter Complementarity (Extended Version)

Understand

The fundamental nature of Dark Matter is a central theme of the Snowmass 2021 process, extending across all frontiers.

• In the last decade, advances in detector technology, analysis techniques and theoretical modeling have enabled a new generation of experiments and searches while broadening the types of candidates we can pursue.
• Over the next decade, there is great potential for discoveries that would transform our understanding of dark matter.
• In the following, we outline a road map for discovery developed in collaboration among the frontiers.
