The discovery of high-energy astrophysical neutrinos and the first hints of coincident
electromagnetic and neutrino emissions opened new opportunities in multi-messenger …

The present white paper is submitted as part of the “Snowmass” process to help inform the
long-term plans of the United States Department of Energy and the National Science …

Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy
physics. With energies far beyond solar, supernovae, atmospheric, and accelerator …

A bstract The interpretation of present and future neutrino experiments requires accurate
theoretical predictions for neutrino-nucleus scattering rates. Neutrino structure functions can …

Neutrinos are one of the most promising messengers for signals of new physics Beyond the
Standard Model (BSM). On the theoretical side, their elusive nature, combined with their …

A bstract Neutrino interactions with protons and neutrons probe their deep structure and may
reveal new physics. The higher the neutrino energy, the sharper the probe. So far, the …

We propose a new probe of cosmic relic neutrinos (CνB) using their resonant scattering
against cosmogenic neutrinos. Depending on the lightest neutrino mass and the energy …

Do neutrinos have sizable self-interactions? They might. Laboratory constraints are weak, so
strong effects are possible in astrophysical environments and the early Universe …

Next-generation ultrahigh-energy (UHE) neutrino telescopes, presently under planning, will
have the potential to probe the decay of heavy dark matter (DM) into UHE neutrinos, with …

The ultrahigh energy range of neutrino physics (above∼ 10 7 GeV), as yet devoid of
detections, is an open landscape with challenges to be met and discoveries to be made …
