Zusammenfassung:
Neutrinos are the Standard Model (SM) particles which we understand the
least, often due to how weakly they interact with the other SM particles.
Beyond this, very little is known about interactions among the neutrinos, i.e.,
their self-interactions. The SM predicts neutrino self-interactions at a level
beyond any current experimental capabilities, leaving open the possibility for
beyond-the-SM interactions across many energy scales. In this white paper, we
review the current knowledge of neutrino self-interactions from a vast array of
probes, from cosmology, to astrophysics, to the laboratory. We also discuss
theoretical motivations for such self-interactions, including neutrino masses
and possible connections to dark matter. Looking forward, we discuss the
capabilities of searches in the next generation and beyond, highlighting the
possibility of future discovery of this beyond-the-SM physics.
