Searches for long-lived particles (LLPs) boost the discovery potential for physics beyond the Standard Model. Exploring particles through their decay length opens up a whole new world of possible particles with different lifetimes, masses and decay modes. The interpretation of such searches, however, is often limited by the underlying model and/or the experimental setup.
This workshop brings together theorists and experimentalists to discuss the physics behind LLPs around the following questions:
- What do LLP searches tell us about the fundamental properties of new particles?
- What is the role of different searches at colliders, beam dump experiments, table-top experiments, in cosmology and astrophysics?
- Are the widely explored ‚portals‘ to a hidden sector enough to cover all possible signatures of LLPs? What other extensions of the Standard Model predict LLPs?
- What do we learn about the big questions in fundamental physics like dark matter, the origin of neutrino masses, baryogenesis, CP violation in and beyond QCD?
- What searches and new experiments do we need in the future to fully explore the theory space of LLPs?
The workshop will take place in a relaxed format with one or two key talks per day and much time for exchange, discussions and research.
