Chiral perturbative solution for the type-I seesaw mechanism in next-to-leading order

Masaki J. S. Yang

In this letter, we perform chiral perturbative diagonalization of the type-I seesaw mechanism by hierarchical singular values $λ_{i}$ of the Dirac mass matrix $m_{D}$ up to the nex…

Allowed region for the (second) lightest mass $M_{1, 2}$ of right-handed neutrino $ν_{R 1, 2}$ with $S O (10)$ -inspired relations and sequential dominance

Masaki J. S. Yang

In this paper, we evaluate the (second) lightest mass $M_{1, 2}$ of right-handed neutrino $ν_{R 1, 2}$ in grand unified theories with the type-I seesaw mechanism that predicts an almo…
