Query: Short-range correlations for neutrinoless double-beta decay and
  low-momentum NN potentials   We approach the calculation of the nuclear matrix element of the neutrinoless
double-beta decay process, considering the light-neutrino-exchange channel, by
way of the realistic shell-model. In particular the focus of our work is
spotted on the role of the short-range correlations, which should be taken into
account because of the short-range repulsion of the realistic potentials. Our
shell-model wave functions are calculated using an effective Hamiltonian
derived from the high-precision CD-Bonn nucleon-nucleon potential, the latter
renormalized by way of the so-called V-low-k approach. The renormalization
procedure decouples the repulsive high-momentum component of the potential from
the low-momentum ones by the introduction of a cutoff Lambda, and is employed
to renormalize consistently the two-body neutrino potentials to calculate the
nuclear matrix elements of candidates to this decay process in mass interval
ranging from A=76 up to A=136. We study the dependence of the decay operator on
the choice of the cutoff, and compare our results with other approaches that
can be found in present literature.
