• Radiative neutrino mass model
• Flavor symmetry

We study the Zee-Babu two loop neutrino mass generation model and look for a possible flavor symmetry behind the tri-bimaximal neutrino mixing We find that there probably exists the mu-tau symmetry in the case of the normal neutrino mass hierarchy whereas there may not be in the inverted hierarchy case We also propose a spec
