Abstract

On the basis of a supersymmetric yukawaon model, Sumino's relation for charged lepton masses is re-derived. A relation between values of K(μ) ≡ (m_e +m_μ+ m_τ)/(√(m_e) + √(m_μ) + √(m_τ))² and κ(μ) ≡ √(m_e m_μm_τ)/ (√(m_e) + √(m_μ)+ √(m_τ))³ is investigated without using a relation K=2/3. Predicted value of κ(μ) is compared with the observed value of κ(μ), and it is concluded that the value ξ(μ)≡ (3/2)K(μ) -1 is of the order of 10^-3 or less.
