The Standard Model teaches us that in the framework of such general principles as local gauge symmetry, unication of weak and electromag- netic interactions and Brout-Englert-Higgs spontaneous breaking of the elec- troweak symmetry nature chooses the simplest possibilities. Two-component left-handed massless neutrino elds play crucial role in the determination of the charged current structure of the Standard Model. The absence of the right-handed neutrino elds in the Standard Model is the simplest, most economical possibility. In such a scenario Majorana mass term is the only possibility for neutrinos to be massive and mixed. Such mass term is gener- ated by the lepton-number violating Weinberg eective Lagrangian. In this approach three Majorana neutrino masses are suppressed with respect to the masses of other fundamental fermions by the ratio of the electroweak scale and a scale of a lepton-number violating physics. The discovery of the neu- trinoless double -decay and absence of transitions of avor neutrinos into sterile states would be evidence in favor of the minimal scenario we advocate here. 1
