A Democratic Seesaw Quark Mass Matrix Related to the Charged Lepton Masses

arXiv:hep-ph/9602303

Abstract

We investigate a seesaw type mass matrix $M_{f} ≃ m_{L} M_{F}^{- 1} m_{R}$ for quarks and leptons, $f$ , under the assumptions that the matrices $m_{L}$ and $m_{R}$ have common structures for the quarks and leptons, and that the matrix $M_{F}$ characterizing the heavy fermion sector has the form [(unit matrix)+ (democratic-type matrix)]. We obtain well-satisfied relations for quark masses and mixings related to the charged lepton masses.
