The Glashow resonance describes the resonant formation of a W− boson during the
interaction of a high-energy electron antineutrino with an electron, peaking at an …

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 …

Abstract The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to
accurately observe ultra-high-energy cosmic rays (UHECRs) and cosmic neutrinos from …

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

We report a measurement of the energy spectrum of cosmic rays above 2.5× 10 18 eV
based on 215 030 events. New results are presented: at about 1.3× 10 19 eV, the spectral …

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 with energies above 1017 eV are detectable with the Surface Detector Array of the
Pierre Auger Observatory. The identification is efficiently performed for neutrinos of all …

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 …

Lorentz invariance violation (LIV) is often described by dispersion relations of the form E2 i=
m2 i+ p2 i+ δi, nE2+n with delta different based on particle type i, with energy E, momentum …

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 …
