Neutrino Facilities as Versatile Probes of New Physics

Current and upcoming neutrino experiments bring unprecedented sensitivity to rare phenomena in particle physics. In this talk, I will discuss how these can test extensions of the Standard Model and how they can shine light on outstanding puzzles like the origin of neutrino masses, the particle nature of dark matter, and how we are currently shining light on unsolved mysteries in neutrino data, like the low-energy electron-like excesses at short-baseline experiments. In doing so, we will see how new physics may show up in measurements across different energy scales, going from MeV scales at spallation sources, to GeV scales at accelerators, and finally the highest energy astrophysical neutrinos at the PeV scale.
