abstract

We present $\nu$DoBe, a Python tool for the computation of neutrinoless double beta decay ($0\nu\beta\beta$) rates in terms of lepton-number-violating operators in the Standard Model Effective Field Theory (SMEFT). The tool can be used for automated calculations of $0\nu\beta\beta$ rates, electron spectra and angular correlations for all isotopes of experimental interest, for lepton-number-violating operators up to and including dimension 9. The tool takes care of renormalization-group running to lower energies and provides the matching to the low-energy effective field theory and, at lower scales, to a chiral effective field theory description of $0\nu\beta\beta$ rates. The user can specify different sets of nuclear matrix elements from various many-body methods and hadronic low-energy constants. The tool can be used to quickly generate analytical and numerical expressions for $0\nu\beta\beta$ rates and to generate a large variety of plots. In this work, we provide examples of possible use along with a detailed code documentation.

    hep-ph 2026-07 accept novelty 8.0 of 10

    First complete tree-level HEFT matching of the type-II seesaw and a Hilbert-series-checked, flavor-complete basis of lepton-number-violating HEFT operators through O(p^4).

  2. Neutrinoless Double-Beta Decays from Operator Mixing

    hep-ph 2026-08 conditional novelty 6.0 of 10

    Renormalization-group mixing lets heavy-quark dimension-seven operators feed neutrinoless double-beta decay, giving some of the strongest current bounds on these new-physics operators.
