A Snowmass Whitepaper: Dark Matter Production at Intensity-Frontier Experiments

Abstract

Dark matter particles can be observably produced at intensity-frontier experiments, and opportunities in the next decade will explore important parameter space motivated by thermal DM models, the dark sector paradigm, and anomalies in data. This whitepaper describes the motivations, detection strategies, prospects and challenges for such searches, as well as synergies and complementarity both within RF6 and across HEP.

arXiv comment37 pages, 13 figures, comments and feedback welcome. Updated discussion of proton beam dump searches, minor edits to text and title for clarity. Core message unchanged
