Despite all its successes, the shortcomings of the Standard Model of particle physics are well-known: for instance the origin of its flavour structure, the absence of a dark matter candidate, or the strong CP problem.
While many of the new physics models aiming at solving them rely on new particles around the TeV scale, this is neither a requirement nor the simplest solution in many cases. In fact, new light but Feebly Interacting Particles (FIPs) often represent the most straightforward solution, with deep implications for flavour physics, dark matter, astrophysics and cosmology. As particle physics enters a new era of “precision”, dozens of experiments, ranging from the High Luminosity LHC to neutrinos experiments, will have the potential to search for such particles.
FlavourFIPs aims at exploring the uncharted links between such versatile new physics candidates and the Standard Model flavour problem.
