Multiple experiments and observations over the previous two decades have strongly constrained the "canonical WIMP" scenario, motivating increased theoretical efforts to study a wider array of potential dark matter candidates. Compared to previous efforts, these studies span a vast range of masses, couplings, cosmological effects and detection signatures; the current status of the field is more complex, but also much richer. Progress will require a detailed theoretical understanding of the many possible direct, indirect, cosmological and collider signatures of "beyond WIMP" models, as well as detailed methods for separating beyond standard model signatures from standard model foregrounds. This workshop brings together leading topical experts spanning cosmology, particle physics, and astrophysics to: (1) better understand the future of dark matter model building, (2) produce novel probes that are better able to constrain well-motivated dark matter models, and (3) develop better cross-disciplinary techniques that probe novel dark matter parameter space. Our goal is to produce a theoretically-motivated roadmap that guides the next decade of experimental and observational dark matter searches.

Scattering amplitudes are central quantities in perturbative quantum field theories, yet many aspects of their mathematical structure remain unexplained. The aim of this workshop is to bring together experts on two aspects of their fundamental structure—the positivity properties they exhibit at the level of amplitude integrands, and the analytic features they manifest after integration—in order to deepen our understanding of how these surprising mathematical features are related. By stimulating further interaction between these communities, we will pave the way towards a new understanding of how the striking, and often defining, analytic features that amplitudes exhibit can be predicted directly from the study of positive geometries. Among other auspicious outcomes, this will have a transformative impact on methods for bootstrapping perturbative scattering amplitudes, which crucially rely on being able to make refined predictions about the analytic structure of individual amplitudes.
