The cross sections for neutrino interactions with nucleons have been measured directly in
accelerator experiments and through the zenith-angle and energy dependence of neutrino …

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 …

In this work we present the interpretation of the energy spectrum and mass composition data
as measured by the Pierre Auger Collaboration above 6× 1017 eV. We use an astrophysical …

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 …

Neutron stars close to the Galactic center are expected to swim in a dense background of
dark matter. For models in which the dark matter has efficient interactions with neutrons, they …

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 …

Ultrahigh-energy (UHE) neutrinos, with EeV-scale energies, carry with them unique insight
into fundamental open questions in astrophysics and particle physics. For 50 years, they …

We test the hypothesis of starburst galaxies as sources of ultrahigh energy cosmic rays and
high energy neutrinos. The computation of interactions of ultrahigh energy cosmic rays in the …

Using the data of the Pierre Auger Observatory, we report on a search for signatures that
would be suggestive of super-heavy particles decaying in the Galactic halo. From the lack of …

Soon, a new generation of neutrino telescopes, presently under planning, will target the
discovery of ultra-high-energy (UHE) neutrinos of cosmic origin, with energies higher than …
