Texture Dirac Mass Matrices and Lepton Asymmetry in the Minimal Seesaw Model with Tri-Bimaximal Mixing

Agus Purwanto, Bintoro Anang Subagyo, Erika Rani

Abstract


We examined the minimal seesaw mechanism of 3 × 2 Dirac matrix by starting our analysis with the masses of light neutrinos with tri/bi-maximal mixing in the basis where the charged-lepton Yukawa matrix and heavy Majorana neutrino mass matrix are diagonal. We found all possible Dirac mass textures which contain one zero
entry or two in the matrix.

Keywords


tri-bimaximal mixing; minimal seesaw model; mass matrices and lepton asymmetry
