We propose a particularly economical and suggestive neutrino mass model, in which there are only two right-handed Majorana neutrinos of O(1) TeV and their masses are highly degenerate. Its novel Yukawa-coupling texture together with the seesaw mechanism allows us to achieve the normal neutrino mass hierarchy with m1 = 0 and a nearly tri-bimaximal neutrino… CONTINUE READING
