Abstract
We discuss the potential of e(-)e(-) collisions at energies comparable to t he masses of heavy Majorana neutrinos to reveal their mass and mixing param eters. This potential is compared with the low-energy environment in neutri noless double beta decay of complex nuclei. We give estimates for the short -range repulsion between any pair of valence quarks bound inside two differ ent nucleons giving rise to suppression factors in the range of 50-100 in a mplitude for decays mediated by heavy flavors.
