Solving the neutrino puzzles through a radiative extended lepton model

Assuming that the actual neutrino puzzles (solar, atmospheric, and providing the HDM of the Universe) are real, and that their “standard” theoretical explanations are implemented by Nature, we propose a natural scenario for generating the required neutrino mass texture. We suppose the existence of a mirror world with the same Standard Model group structure and particle content for both the ordinary and the mirror world. The various one-loop neutrino masses are evaluated and are found to give a good overall agreement with the phenomenologically required values.
