$\nu$DoBe -- A Python Tool for Neutrinoless Double Beta Decay

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. The code can be accessed through: GitHub: https://github.com/OScholer/nudobe Online User-Interface: https://nudobe.streamlit.app
