“Ant” and “whale” have the same “father” !? Neutrino mass might be generated in a different way

Scale suppression (e.g. Seesaw) Familiar way An oasis Loop mechanism (dim.-5 opperator) e.g. Suppression via not the loop factor but a product of (Yukawa) couplings. What kinds of products?

Simplifications in this Talk

New Fermions : Only for Dirac neutrinos New Scalars : Yukawa Int. with only leptons (Colorless, integer electric charge) Symmetry : SM gauge sym. No unbroken (no ) (All neutral scalars have VEV.) (No dark matter candidates.) Negligible mixings
