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

Abstract

We investigate a seesaw type mass matrix $M_f\simeq m_L{M}_F^{-1}{m}_R$ 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.
