Yukawaon approach to the Sumino relation for charged lepton masses

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)≡(me+mμ+mτ)/(me+mμ+mτ)2 and κ(μ)≡memμmτ/(me+mμ+mτ)3 is investigated without using the relation K=2/3. Predicted value of κ(μ) is compared with the observe...

Zusammenfassung:	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)≡(me+mμ+mτ)/(me+mμ+mτ)2 and κ(μ)≡memμmτ/(me+mμ+mτ)3 is investigated without using the 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.
