A Democratic Seesaw Quark Mass Matrix Related to the Charged Lepton Masses
Yoshio Koide, Hideo Fusaoka
Abstract
We investigate a seesaw type mass matrix Mf mL MF-1 mR for quarks and leptons, f, under the assumptions that the matrices mL and mR have common structures for the quarks and leptons, and that the matrix MF 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.
