Abstract:
We consider the possibility that neutrinoless double beta decay may occur in models with unbroken lepton number via the emission of a massive gauge boson with electron lepton number 2-2. We determine the shape of the ββ\beta\,\beta sum energy spectrum as a function of the gauge coupling, independent of model-specific details. We discuss our results in light of the persistent experimental claims that excess events are observed near but below the spectrum endpoint of several elements.
