text: If the right-handed neutrinos are very heavy, they induce a very small mass for the left-handed neutrinos, which is proportional to the reciprocal of the heavy mass.
text: According to GUTs and left-right models, the right-handed neutrino is extremely heavy: M N H L ≈ {\textstyle M_{NHL}\approx } 105 to 1012 GeV, while the smaller eigenvalue is approximately equal to
