abstract

A search for mixing between active neutrinos and light sterile neutrinos has been performed by looking for muon neutrino disappearance in two detectors at baselines of 1.04 km and 735 km, using a combined MINOS and MINOS+ exposure of $16.36\times10^{20}$ protons-on-target. A simultaneous fit to the charged-current muon neutrino and neutral-current neutrino energy spectra in the two detectors yields no evidence for sterile neutrino mixing using a 3+1 model. The most stringent limit to date is set on the mixing parameter $\sin^2\theta_{24}$ for most values of the sterile neutrino mass-splitting $\Delta m^2_{41} > 10^{-4}$ eV$^2$.

  1. Effective Matter Flavor Conversion Mediated by Pseudo-Sterile States as the Possible Origin of Neutrino Oscillation Anomalies

    hep-ph 2026-05 conditional novelty 6.0 of 10

    A sterile neutrino with a novel density-dependent matter potential Vs resolves multiple oscillation anomalies when Vs is negative and mixing angles are small.

  2. 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.

  3. Constraining axial non-standard neutrino interactions with MINOS and MINOS+

    hep-ph 2025-09 unverdicted novelty 6.0 of 10

    MINOS and MINOS+ neutral-current data yield world-leading bounds on axial NSI couplings ε^{Aq}_{eτ} and ε^{Aq}_{ττ} (including the isospin-singlet combination) for neutrinos interacting with u and d quarks.

  4. Electroweak right-handed neutrino portal dark matter

    hep-ph 2025-12 conditional novelty 5.0 of 10

    In neutrino-portal dark matter, ignoring internal dark-sector interactions during freeze-in can underestimate the final relic abundance by 30–95%.

  5. Neutrino Masses from the Point of View of Economy and Simplicity

    hep-ph 2019-07 unverdicted novelty 2.0 of 10

    Neutrino masses are unlikely to share the Standard Model origin of other fermion masses, with the Weinberg effective Lagrangian providing the simplest beyond-Standard-Model mechanism for small Majorana masses.
