We study generalized neutrino interactions (GNI) for several neutrino processes, including neutrinos from electron-positron collisions, neutrino-electron scattering, and neutrino deep inelastic scattering. We constrain scalar, pseudoscalar, and tensor new physics effective couplings, based on the standard model effective field theory at low energies. We have performed a global analysis for the different effective couplings. We also present the different individual constraints for each effective parameter (scalar, pseudoscalar, and tensor). Being a global analysis, we show robust results for the restrictions on the different GNI parameters and improve some of these bounds.

  1. Towards a complete scheme of cosmological neutrino self-interactions: Collision term for a wide range of mediator masses

    hep-ph 2026-02 unverdicted novelty 6.0

    A new scheme for the neutrino collision term valid from light to heavy mediator regimes, with smooth transition as the universe cools, for scalar-mediated NSI in Dirac and Majorana cases.

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

    hep-ph 2026-06 unverdicted novelty 5.0

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

  3. Generalized Neutrino Interactions: constraints and parametrizations

    hep-ph 2026-02 unverdicted novelty 4.0

    Relating two GNI parametrizations shows scalar neutrino-quark interactions are more tightly constrained by COHERENT while tensor interactions are better bounded by deep inelastic scattering.
