Feebly Interacting Particles (FIPs) are any new physics with coupling <<< 1.

With the establishment and maturation of the experimental programs searching for strongly-coupled physics at the LHC, there is an increasing interest in the broader particle and astrophysics community for feebly-interacting particles as a paradigm complementary to the strongly interacting sector at the TeV (or beyond) scale.

There are a multitude of initiatives that reflect the profound interest into this emerging field, including the LHC Long-Lived Particle Community workshops and white paper, the Physics Beyond Colliders initiative at CERN, recent studies for present and future neutrino experiments, and the recently published Briefing Book of the European Strategy update.

As a result, the time is ideal to hold a workshop fully dedicated to FIPs.

The main goal of the workshop will be to bring together experts from collider, beam dump, fixed target, astrophysics, axions/ALPs searches; current/future neutrino experiments; and dark matter direct and indirect detection communities to discuss progress in experimental searches and underlying theory models and to enhance the exchange and cross-fertilization across different fields.

The following topics will be addressed:

  • Standard Model problems and FIPs from theoretical perspectives
  • Dark matter: what we know about it from a cosmological viewpoint, overview of models, status and prospects of collider, direct, and indirect detection experiments
  • Experimental techniques for searching for FIPs at accelerator-based experiments.
  • Very low-mass (< 100 eV) FIPs
  • Stellar, astrophysical, and cosmological constraints on FIPs
  • Heavy neutral leptons and their relationships to leptogenesis, astrophysics, cosmology, SM neutrino physics.
  • Light dark matter and corresponding mediators, including axions/ALPs: phenomenology, searches at accelerator-based experiments, helioscopes, haloscopes, relationship to astrophysics and cosmology.

We look forward to welcoming you online for FIPs 2020.
