A formula by decomposition for the minimal type-I seesaw mechanism and conditions of symmetry in an arbitrary basis
Masaki J. S. Yang
In this paper, defining a formula by decomposition for the minimal type-I seesaw mechanism, we obtain conditions of symmetry for the neutrino mass matrix in an a…
Almost exact diagonal reflection symmetries and three-zero texture
Masaki J. S. Yang
In this paper, we consider a three-zero texture with diagonal reflection symmetries in the SM. The three-zero texture has two less assumptions ()…
Resolving the Hubble tension in a U(1) model with Majoron
Takeshi Araki, Kento Asai, Kei Honda +4
In this paper, we explore possibilities of resolving the Hubble tension and anomaly simultaneously in a U(1) model with Majoron. We only focus on a case wher…
Diagonal reflection symmetries and universal four-zero texture
Masaki J. S. Yang
In this paper, we consider a set of new symmetries in the SM, {\it diagonal reflection} symmetries with diag $(-1,1…
Interplay between - reflection symmetry, four-zero texture and universal texture
Masaki J. S. Yang
In this letter, we consider exact reflection symmetries for quarks and leptons. Fermion mass matrices are assumed to be four-zero textures for charged fermions an…
Lopsided texture compatible with thermal leptogenesis in partially composite Pati--Salam unification
Masaki J. S. Yang
In this paper, we consider a lopsided flavor texture compatible with thermal leptogenesis in partially composite Pati--Salam unification. The Davidson--Ibarra bound $M_{νR1} \gtrsi…
