Light sterile neutrinos with masses at the sub-eV or eV scale are hinted by current experimental and cosmological data. Assuming the Majorana nature of these hypothetical particles, we discuss their effects in the neutrinoless double beta decay by exploring the implications of a vanishing effective Majorana neutrino mass. Allowed ranges of neutrino masses, mixing angles and Majorana CP-violating phases are illustrated in some instructive cases for both normal and inverted mass hierarchies of three active neutrinos.

  1. Neutrinoless double beta decay with light sterile neutrinos: the contact terms

    hep-ph 2024-12 conditional novelty 7.0 of 10

    The short-range nuclear contact term in neutrinoless double beta decay depends on sterile neutrino mass more strongly than previously assumed, lengthening predicted half-lives by up to about a factor of six.

  2. 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.

  3. Right-handed neutrinos: seesaw models and signatures

    hep-ph 2025-02 conditional novelty 1.0 of 10

    A pedagogical review that explains how adding right-handed neutrinos can generate small neutrino masses through seesaw mechanisms and what experimental signatures such models predict.
