Motivated by the discovery of the first high-energy astrophysical neutrino source, the blazar TXS 0506+056, we revisit the IceCube flavor ratio analysis. Assuming large statistics from identified blazars, collected in the forthcoming years by the IceCube detector and its successor IceCube-Gen2, we demonstrate that the constraints on several new physics scenarios in which the baseline dependent terms in neutrino oscillation probabilities are not averaged, can be improved. As a representative case, we consider pseudo-Dirac neutrinos while neutrino decay is also discussed.

  1. Probing Neutrino Flavor Composition with the Glashow Resonance at Tau Air-Shower Neutrino Telescopes

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Tau air-shower telescopes can potentially measure the PeV \bar{\nu}_e/(\nu_\tau+\bar{\nu}_\tau) ratio via the Glashow resonance, but standalone sensitivity only clearly separates \bar{\nu}_e-rich sources from standard...

  2. Are neutrinos Majorana? Fixed-target and high-energy astrophysical searches decide

    hep-ph 2026-06 unverdicted novelty 6.0 of 10

    Correlated HNL discovery at SHiP and flavor ratio shifts in astrophysical neutrinos at telescopes would establish neutrinos as Majorana fermions.

  3. Boomerang mechanism explaining the excess radio background

    hep-ph 2025-09 conditional novelty 6.0 of 10

    A two-stage mechanism where relic neutrinos convert to dark neutrinos in the early universe and later decay into photon states can explain the ARCADE 2 excess radio background while evading neutrino magnetic moment bounds.

  4. Probing Scalar Non-Standard Neutrino Interactions using High-Energy Astrophysical Neutrinos

    hep-ph 2026-06 unverdicted novelty 5.0 of 10

    IceCube astrophysical neutrino data is analyzed for flavor ratios and spectral shapes to constrain scalar non-standard neutrino interactions via induced pseudo-Dirac behavior.
