I present a novel mode of neutrinoless double beta decay with emission of a light Majoron-like scalar particle $\phi$. We assume it couples via an effective seven-dimensional operator with a $(V+A)$ lepton current and $(V\pm A)$ quark currents leading to a long-range contribution that is unsuppressed by the light neutrino mass. Calculating the total double beta decay rate and determine the...

Neutrinoless double beta decay is usually considered a probe for Majorana neutrino masses. However, there are many other potential contributions to the total decay amplitude. In this talk, I will summarize a number of recent papers on such "exotic" contributions to double beta decay.

Observable effects of the Lorentz violation symmetry at low energy scale can also be investigated by comparing the theoretical calculations with precise analysis of the measured summed energy spectra of electrons emitted in two-neutrino double beta decay (DBD) mode. In this study we make a detailed comparison of the phase space factors (PSF) and their differentials computed with analytical...
