We derive simple analytical formulae for the renormalization group running of neutrino masses, leptonic mixing angles and CP phases, which allow an easy understanding of the running. Particularly for a small angle theta_13 the expressions become very compact, even when non-vanishing CP phases are present. Using these equations we investigate: (i) the influence of Dirac and Majorana phases on the evolution of all parameters, (ii) the implications of running neutrino parameters for leptogenesis, (iii) changes of the mass bounds from WMAP and neutrinoless double beta decay experiments, relevant for high-energy mass models, (iv) the size of radiative corrections to theta_13 and theta_23 and implications for future precision measurements.

  1. Running of neutrino mass parameters in the Zee model

    hep-ph 2025-12 conditional novelty 6.0 of 10

    In the Zee model, one-loop EFT running—not direct matching—generates the neutrino mass matrix, and 1% variations in fitted high-scale couplings shift neutrino observables beyond next-generation experimental precision.

  2. RG Running of Multiple Neutrino Mixing Parameters at Oscillation Experiments

    hep-ph 2026-06 unverdicted novelty 5.0 of 10

    Combining DUNE-ND, JUNO-TAO, and FASERν2 data can disentangle multiple model-independent RG running parameters of neutrino mixing and resolve degeneracies.

  3. Testing the RG Running of the Leptonic Dirac CP Phase with Reactor Neutrinos

    hep-ph 2024-11 conditional novelty 5.0 of 10

    The JUNO-TAO reactor experiment could constrain the renormalization-group running beta function of the Dirac CP phase to about βδ ≈ 0.1, if spectrum-shape systematics are controlled.
