Neutrinoless Double Beta Decay with Negligible Neutrino Mass
arXiv:hep-ph/0202262 · doi:10.1016/S0370-2693(02)01869-5
Abstract
If the electron neutrino has an effective nonzero Majorana mass, then neutrinoless double beta decay will occur. However, the latter is possible also with a negligible neutrino mass. We show how this may happen in a simple model of scalar diquarks and dileptons. This possibility allows neutrino masses to be small and hierarchical, without conflicting with the possible experimental evidence of neutrinoless double beta decay.
