We determine the elements of the leptonic mixing matrix, without assuming unitarity, combining data from neutrino oscillation experiments and weak decays. To that end, we first develop a formalism for studying neutrino oscillations in vacuum and matter when the leptonic mixing matrix is not unitary. To be conservative, only three light neutrino species are considered, whose propagation is generically affected by non-unitary effects. Precision improvements within future facilities are discussed as well.

    hep-ph 2025-02 conditional novelty 6.0 of 10

    Analytic expressions for T violation are derived for standard neutrino oscillations, nonstandard interactions, and unitarity violation, with different energy dependences that could distinguish new physics.

    hep-ph 2019-08 conditional novelty 6.0 of 10

    Adding right-handed neutrinos to the Froggatt-Nielsen 331 model realizes a double seesaw with sub-eV active neutrinos, keV sterile neutrinos, and TeV-scale heavy neutrinos that fits oscillation data in three benchmark points.

  6. Family-separated seesaw relations of Majorana neutrinos

    hep-ph 2026-05 unverdicted novelty 5.0 of 10

    A family-separated solution to the exact seesaw equation yields per-family relations between light and heavy Majorana neutrino parameters.

  7. Impact of matter effects on the unitarity test of lepton mixing

    hep-ph 2026-05 unverdicted novelty 5.0 of 10

    The authors examine extraction of lepton mixing matrix elements from spectral data in neutrino oscillation experiments including matter effects and test unitarity via a vanishing quantity in a four-generation model.

  8. Testing the unitarity of the light neutrino mixing matrix

    hep-ph 2026-03 conditional novelty 5.0 of 10

    PMNS non-unitarity would make W+W- production cross sections grow anomalously with energy; LEP data already bound δ_e ≲ 0.0135 and future colliders could reach ~10^-5.

  9. Probing non-unitarity of the PMNS matrix in P2SO and comparison with DUNE

    hep-ph 2026-03 conditional novelty 5.0 of 10

    Projected GLoBES sensitivities show DUNE constrains the non-unitarity parameters α11 and |α21| better, while P2SO wins on α33 (and marginally α22); non-unitarity also distorts mass-hierarchy, octant, and CP-violation ...

    hep-ph 2019-08 conditional novelty 5.0 of 10

    A new first-order perturbation theory for solar-scale neutrino oscillations with non-unitary mixing shows that δ and the non-unitarity α parameters form physical, convention-independent phase correlations.

    hep-ph 2025-02 conditional novelty 3.0 of 10

    Large neutrino mixing is not fixed by the seesaw mechanism's mass eigenvalues, so it must arise from additional flavor structure, and the inverse seesaw needs a fine-tuned cancellation.

    A single keV sterile neutrino in the minimal extended seesaw with A4 flavor symmetry is scanned against 0νββ, dark matter, and leptogenesis constraints, and the normal neutrino mass ordering emerges as favored.
