Description
In this talk, we will review the Koide formula for charged lepton masses, and its possible explanation based on scalar potential models and from supersymmetric Yukawaon models. We present a modified version of the Koide formula derived from both models. The scalar potential in the scalar potential model or the superpotential in the Yukawaon model is constructed with all terms invariant under symmetries. The resulting Koide's character is modified by two effective parameters, and can fit the experimental mass data of charged leptons, up quarks and down quarks.
