Chiral perturbative relation for neutrino masses in the type-I seesaw mechanism
In this letter, we perform a perturbative analysis by the lightest singular value mD1 of the Dirac mass matrix mD in the type-I seesaw mechanism. A mass relation M1=mD12/|(mν)11| is obtained for the lightest mass M1 of the right-handed neutrino νR1 and the mass matrix of the left-handed neutrinos mν...
