abstract

We discuss the acceptance and sensitivity of a small air-shower imaging system to detect earth-skimming ultrahigh-energy tau neutrinos. The instrument we study is located on top of a mountain and has an azimuthal field of view of $360^\circ$. We find that the acceptance and sensitivity of such a system is close to maximal if it is located about 2 km above ground, has a vertical field of view of $5^\circ$, allows the reconstruction of an at least $0.3^\circ$ long air-shower image, and features an effective light-collection area of $10$ m$^2$ in any direction. After three years of operation, an imaging system with these features achieves an all-flavor neutrino flux sensitivity of $5\times10^{-9}$ GeV cm$^{-2}$ s$^{-1}$ sr$^{-1}$ at $2\times10^8$ GeV.

  1. Rare processes in ultrahigh-energy tau-lepton transport

    hep-ph 2026-07 accept novelty 7.0 of 10

    Tau leptons at EeV energies produce muon pairs and neutral pions via rare processes, with energy-loss rates only ~0.6% and ~0.2% of electron pair production, yet muon pairs may yield detectable double-track signatures.

  2. Astrophysical Neutrino Sources as Colliders

    hep-ph 2026-07 conditional novelty 7.0 of 10

    Neutrino point-source observations (IceCube, KM3NeT) can bound inelastic pp and pγ cross sections from √s ≈ 1 GeV to ~10^5 GeV, extending beyond LHC/HERA and sometimes below unitarity limits.

  3. Constraining self-interacting ultrahigh-energy muon neutrinos by cosmic microwave background spectral distortion

    astro-ph.CO 2025-06 conditional novelty 4.0 of 10

    Scalar-mediated scattering of PeV muon neutrinos on the cosmic neutrino background injects photon energy that distorts the CMB, giving coupling bounds g_nu_mu of about 10^-4 to 10^-5 with projected PIXIE sensitivities...

  4. Particle Astrophysics with High and Ultrahigh Energy Neutrinos

    astro-ph.HE 2025-11 unverdicted novelty 2.0 of 10

    Recent high and ultrahigh energy neutrino detections open a new observational window to the universe by revealing sources and processes inaccessible via photons.
