Charged Lepton Mass Spectrum and a Scalar Potential Model

Abstract

Stimulated by a recent work by Sumino, on the basis of a model in which effective Yukawa coupling constants are described by vacuum expectation values of a scalar $\Phi$ with $3\times 3$ components, a possible form of the scalar potential $V(\Phi )$ which can well describe the observed charged lepton mass spectrum is investigated without referring to a specific flavor symmetry model. A general relation among eigenvalues of <\Phi> is derived without referring to an explicit form of $V(\Phi )$.
