Query: Analysis of mechanisms that could contribute to the neutrinoless
  double-beta decay   Neutrinoless double-beta decay, if observed, would signal physics beyond the
Standard Model that could be discovered at energies significantly lower than
those at which the relevant degrees of freedom could be excited. Therefore, it
could be challenging to further use the neutrinoless double-beta decay
observations to distinguish between many beyond Standard Model mechanisms
contributing to this process. Accurate nuclear structure calculations of the
nuclear matrix elements necessary to analyze the decay rates could be helpful
to narrow down the list of contributing mechanisms, and to better identify the
more exotic properties of the neutrinos. We investigate the information one can
get from the angular and energy distribution of the emitted electron assuming
that the right-handed currents exist. For the analysis of these distributions
we calculate the necessary nuclear matrix elements using shell model
techniques.
