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 of the Dirac mass matrix up to the nex…

Contribution of Majoron to Hubble tension in gauged U(1) Model

Kento Asai, Tomoya Asano, Joe Sato +1

In this paper, we analyze parameter regions that can alleviate the Hubble tension in the U(1) model with the broken lepton number U(1) symmetry. As new particles,…

Model Building by Coset Space Dimensional Reduction Scheme Using Twelve-Dimensional Coset Spaces

Kento Asai, Joe Sato, Ryosuke Suda +2

We investigate the twelve-dimensional gauge-Higgs unification models with an eight-dimensional coset space. For each model, we apply the coset space dimensional reduction procedure…

expansion of the type-I seesaw mechanism and partial symmetry for TM mixing

Masaki J. S. Yang

We consider an expansion of the type-I seesaw mechanism by the inverse of the 3-3 matrix element of the mass matrix of right-handed neutrinos . Conditions o…

A general formula by decomposition for the type-I seesaw mechanism

Masaki J. S. Yang

By performing an approximate spectral decomposition to the inverse mass matrix of the right-handed neutrinos , we obtain a basis-independent formula for the type-I seesaw m…
