Understanding the nature of dark matter (DM) is a major open question in particle physics. Large fundamental questions about DM and its physical origin, structure, and evolution remain. The dark sector encapsulates a diverse set of theoretical ideas for DM, ranging from ultralight candidates to primordial structures as massive as stars. Experimentally, this prospective mass range requires efforts that range from table top experiments to international space missions; the vastness of this makes a comprehensive hunt for DM challenging.

Responding to this challenge, we will convene a diverse community of researchers which includes theorists, observers, and experimentalists in this conference. The overarching goal of this conference is to develop new strategies for discovering the physics of dark sectors  by taking advantage of the diverse strengths and interests of the collective.

This meeting will take an innovative approach to solving the problems at hand by promoting discussion and action, and serve as the jumping off point for future work supporting equity, diversity, and inclusion in particle physics.
